DETAIL: Beware! The vast majority of alexandrite offered in the USA is synthetic. The American Gemological Institute estimates that less than 1 in every 100,000 Americans has ever even seen genuine, natural alexandrite. These are two very beautiful, brilliant, rare, natural purple to pink (color change) alexandrite gemstone which originated in Tanzania. The gemstones were hand crafted and faceted by a Russian artisan, following in the footsteps of a centuries-old heritage renown for the production of the elaborate gemstones and jewelry of the Czars of Medieval, Renaissance, and Victorian Russia. As you can see in these photo enlargements, the gemstones are absolutely clean to the unaided eye. Though in a 30x microscope it is possible to discern some small colorless crystals within the gemstones (by the way establishing that they are certainly natural), even in the accompanying photo enlargements it is not possible to discern any blemishes. They may be confidently described as “eye clean”.

The gemstones are purple in color, when they are so inclined, at least. This is the color you will observe when the gemstone is outdoors or under fluorescent lighting. However under strong indoor (incandescent) light, indoors for instance, the stones magically transform themselves into a bright raspberry-pink hue. No matter what light source we used to image these gemstones, whether scanner or camera, they turned color. In hand, out of doors, they are most assuredly purple. But the charm of these remarkable gemstones, at least in the higher qualities, is the dramatic color change they are capable of. And true to its reputation, the light of the camera turned these precious gemstones raspberry pink! The color depends upon the light source (color spectrum) and intensity/brightness. These remarkable gemstones are capable of both of those colors, true chameleons, quite an extraordinary pair of precious gemstones.

These fascinating and colorful gemstones originated in Tanzania, and were hand crafted into these sparkling faceted round cut gemstones in Yekaterinburg, Russia, the fabled land of the incredibly sophisticated, sumptuous gemstones and jewelry of the Czars. They are gorgeous gemstones, full of fire and sparkle, vibrant, and possessing good clarity and color. They are truly special gemstones, quite rare. Most alexandrite, as you might know, generally show green under fluorescent or sun light, then change to red or purple (or some derivative shade) under incandescent or candle light. However some alexandrite (principally from Tanzania) has been found, as these gemstones, to exhibit a purple color which changes to a vivid, almost neon pink under incandescent lighting. These gemstones are so clean, and the colors so uncommon and so vivid, that we weren’t entirely confident that they were natural…until we tested them and found unmistakable evidence that they were indeed natural alexandrite (their refractive index, specific gravity, etc., and the presence of minute colorless crystals when examined in a microscope).

The earring settings are of contemporary origin. They are high quality settings manufactured by one of the USA’s leading semi-custom mount producers. They are constructed of sterling silver; they are not cheap, silver electroplated earrings. It is genuine sterling silver, designed to last a lifetime. It's a first-class piece of jewelry throughout. There are many other setting styles available (euro clicks, lever backs, kidney wires, ball/stud dangles) which, in sterling silver, could be substituted for either no or nominal extra cost. Please write us, ask, we can send you photos of the various alternative earring styles available. We can also reset the gemstones into 14kt solid gold or 14kt gold fill upon request.

As might be expected under magnification the gemstones show the unmistakable, hallmark characteristics of having been hand crafted. The coarseness of the handcrafted finish is considered appealing to most gemstone aficionados, and is not considered a detriment, or detract from the value of such gemstones. These characteristics are not only expected of hand-finished gemstones, many believe that such hand-crafted gemstones possess much greater character and appeal than today's mass-produced, laser-cut gemstones. Unlike today’s computer controlled machine produced gemstones that approach flawlessness in a perfect finish, the cut and finish of handcrafted gemstones like these is the legacy of the artisan who crafted them.

Handcrafted though they may be the gemstones possess great luster and sparkle, and to the eye are completely transparent, but one cannot say with absolute certainty that they are absolutely flawless. True, any blemishes they possess are not visible to the naked eye, and even when magnified as in the accompanying photo enlargements (or under a jeweler’s loupe) there are no discernible flaws. However we hesitate to use the word “flawless”, as sooner or later blemishes will show up at higher levels of magnification with almost every natural gemstone. An absolutely flawless gemstone is very rare in nature (and usually turns out to be synthetic). However to use trade jargon the gemstones can be characterized as "eye clean".

To the eye they are indeed flawless, nonetheless close examination with a jeweler’s loupe will however reveal occasional slight irregularities in the faceting and finish. Of course these characteristics are to be expected of natural, hand-finished gemstones. However for most, the unique nature and character of these handcrafted gemstones more than makes up for any minute blemishes found within the gemstones, as well as the cutting irregularities common to handcrafted gemstones, all of which are by and large (if at all) are only visible under magnification.

ALEXANDRITE HISTORY: Alexandrite is known as a "color change" gemstone. It is emerald green in daylight or under fluorescent lighting, and a purplish red or blue under incandescent lighting, candlelight, or twilight. It belongs to the chrysoberyl family of gems, and one of the most extraordinary types is a cats-eye variety of alexandrite, possessing a remarkably prominent "cat's eye". Most sources credit the discovery of this very unique gemstone to the year 1830 on the birthday of Prince (and ultimately Czar) Alexander II in the Ural Mountains of Russia, near the city of Ekaterinburg. In celebration of Prince Alexander's coming-of-age, this remarkable gemstone was named after him. Alexandrite was popular in Imperial Russia both with the royal family and the wealthy elite, both because of its association with the Czar, and because red and green were the colors of the Russian Empire (and its flag).

However this most rare stone did not bring to Alexander the good fortune it is now generally associated with. Upon ascending to the throne of Russia, Alexander II began long-awaited reforms, including abolishing serfdom, a deed that earned him the name of “The Liberator”. But a terrorist’s bomb ended his life. In memoriam of the monarch who passed away so prematurely, many people in Russia started to wear alexandrite jewelry. It was considered to be the symbol of loyalty to the throne and compassion towards the victims of the revolutionary terror, but at the same time, it said a lot about the owner’s fortune and social position. Even in those times, it was quite difficult to buy an alexandrite ring. According to Leskov, “there were people who made quite an effort to find an alexandrite, and more often, they failed than succeeded.”

Alexandrite is well known to be an extremely scarce and very costly gem. The quality of color change with different illumination is the primary basis for its quality and price. According to the Gemstone Institute of America (“GIA”), no more than one person out of 100,000 has ever seen a natural alexandrite gemstone, although synthetic alexandrite is common and widely available. It is likely that if you read the fine print of 99% of the Alexandrite offered at retail jewelers, you will find it to be "laboratory produced" - synthetic. If there is a huge color change from a very intense green to a very intense red/purple, you can be 99.9% sure that both the color change and the gemstone itself is synthetic. The shift in color of natural gemstones is generally much more subtle. Kind of like the difference in taste between fruit juice and Kool-Aide. One is subtle and natural, the other brassy and synthetic.

However even as an artificially grown stone, alexandrite often commands a retail price of $300.00 to $500.00 per carat. Of course, alexandrite can be found in Russian jewelry of the imperial era, as it was well loved by the Russian master jewelers. Master gemologist George Kunz of Tiffany was a fan of alexandrite, and the company produced many rings featuring fine alexandrite in the late nineteenth and early twentieth century, including some set in platinum from the twenties. Some Victorian jewelry from England featured sets of small alexandrite. However the original source in Russia's Ural Mountains has long since closed after producing for only a few decades, and only a few stones can be found on the Russian market today.

In the past few decades some very small deposits of alexandrite have been discovered in Brazil, Sri Lanka, Zimbabwe, Tanzania, India, and Mozambique. However the Brazilian gemstones tend to have washed out colors when cut, and the African and Celanese sources produce very dark, not brightly colored gemstones. The alexandrite from India tends to be very low quality, with limited color change. The cut alexandrite originating from Russia is usually "harvested" from vintage jewelry. For over a century this source of "recycled" gemstones from Russia was the only source of Alexandrite, and for many years, alexandrite was almost impossible to find because there was so little available. Russian Alexandrite remains elusive. A few specimens are still found from time-to-time in the Ural Mountains of Russia, and are sometimes available as an unset stone, but it is extremely rare in fine qualities.

Stones over 5 carats are almost unknown, though the Smithsonian in Washington D.C., owns a 66 carat specimen, which is believed to be the largest cut alexandrite in existence. The colors within alexandrite are due to trace amounts of the mineral impurities iron, titanium, and chromium (and rarely vanadium is also present). As is the case with emerald, the chromium element both giveth and taketh away. While chromium is responsible both for the green color as well as the color change characteristics of alexandrite, chromium also causes alexandrite (like emerald and ruby) to be characterized by fissures and fractures within the gemstone. Just as emerald is treated under high pressure with oil, in recent years newly-mined alexandrite has oftentimes similarly treated under high pressure with a fluxing agent such as resin, wax, or borax.

The tiny crevasses and fractures are then filled with this material under high pressure, and the treatment is generally very difficult to detect outside of the laboratory. However whereas emerald (and ruby) are routinely treated, alexandrite is only occasionally (and only recently) afforded such treatment. The treatment is a recent development, and was not used on gemstones produced in the nineteenth century. In Russia alexandrite is thought to bring luck, good fortune and love, and also to allow the wearer to foresee danger. It is also believed to encourage romance, and to strengthen intuition, creativity, and imagination. Alexandrite is also believed to be beneficial in the treatment of leukemia. On the metaphysical plane, alexandrite is believed useful in reinforcing one's self esteem and balancing positive and negative energy.

HISTORY OF SILVER: After gold, silver is the metal most widely used in jewelry and the most malleable. The oldest silver artifacts found by archaeologists date from ancient Sumeria about 4,000 B.C. At many points in the ancient world, it was actually more costly than gold, particularly in ancient Egypt. Silver is found in native form (i.e., in nuggets), as an alloy with gold (electrum), and in ores containing sulfur, arsenic, antimony or chlorine. Much of the silver originally found in the ancient world was actually a natural alloy of gold and silver (in nugget form) known as “electrum”.

The first large-scale silver mines were in Anatolia (ancient Turkey) and Armenia, where as early as 4,000 B.C. silver was extracted from lead ores by means of a complicated process known as “smelting”. Even then the process was not perfect, as ancient silver does contain trace elements, typically lead, gold, bismuth and other metals, and as much as a third of the silver was left behind in the slag. However measuring the concentrations of the “impurities” in ancient silver can help the forensic jewelry historian in determining the authenticity of classical items. From Turkey and Armenia silver refining technology spread to the rest of Asia Minor and Europe.

By about 2,500 B.C. the Babylonians were one of the major refiners of silver. Silver “treasures” recovered by archaeologists from the second and third millenniums demonstrate the high value the ancient Mediterranean and Near East placed upon silver. Some of the richest burials in history uncovered by archaeologists have been from this time frame, that of Queen Puabi of Ur, Sumeria (26th century B.C.); Tutankhamun (14th century B.C.), and the rich Trojan (25th century B.C.) and Mycenaean (18th century B.C.) treasures uncovered by Heinrich Schliemann.

The ancient Egyptians believed that the skin of their gods was composed of gold, and their bones were thought to be of silver. When silver was introduced into Egypt, it probably was more valuable than gold (silver was rarer and more valuable than gold in many Mesoamerican cultures as well). In surviving inventories of valuables, items of silver were listed above those of gold during the Old Kingdom. Jewelry made of silver was almost always thinner than gold pieces, as indicated by the bracelets of the 4th Dynasty (about 2,500 B.C.) Queen Hetephere I, in marked contrast to the extravagance of her heavy gold jewelry.

A silver treasure excavated by archaeologists and attributable to the reign of Amenemhat II who ruled during the 12th Dynasty (about 1900 B.C.), contained fine silver items which were actually produced in Crete, by the ancient Minoans. When the price of silver finally did fall due to more readily available supplies, for at least another thousand years (through at least the 19th dynasty, about 1,200 B.C.) the price of silver seems to have been fixed at half that of gold. Several royal mummies attributable to about 1,000 B.C. were even entombed in solid silver coffins.

Around 1,000 B.C. Greek Athenians began producing silver from the Laurium mines, and would supply much of the ancient Mediterranean world with its silver for almost 1,000 years. This ancient source was eventually supplemented around 800 B.C. (and then eventually supplanted) by the massive silver mines found in Spain by the Phoenicians and their colony (and ultimate successors) the Carthaginians (operated in part by Hannibal’s family). With the defeat of Carthage by Rome, the Romans gained control of these vast deposits, and mined massive amounts of silver from Spain, stripping entire forests regions for timber to fuel smelting operations. In fact, it was not until the Middle Ages that Spain’s silver mines (and her forests) were finally exhausted.

Although known during the Copper Age, silver made only rare appearances in jewelry before the classical age. Despite its infrequent use as jewelry however, silver was widely used as coinage due to its softness, brilliant color, and resistance to oxidation. Silver alloyed with gold in the form of “electrum” was coined to produce money around 700 B.C. by the Lydians of present-day Turkey. Having access to silver deposits and being able to mine them played a big role in the classical world. Actual silver coins were first produced in Lydia about 610 B.C., and subsequently in Athens in about 580 B.C.

Many historians have argued that it was the possession and exploitation of the Laurium mines by the Athenians that allowed them to become the most powerful city state in Greece. The Athenians were well aware of the significance of the mining operations to the prosperity of their city, as every citizen had shares in the mines. Enough silver was mined and refined at Laurium to finance the expansion of Athens as a trading and naval power. One estimate is that Laurium produced 160 million ounces of silver, worth six billion dollars today (when silver is by comparison relatively cheap and abundant). As the production of silver from the Laurium mines ultimately diminished, Greek silver production shifted to mines in Macedonia.

Silver coinage played a significant role in the ancient world. Macedonia’s coinage during the reign of Philip II (359-336 B.C.) circulated widely throughout the Hellenic world. His famous son, Alexander the Great (336-323 B.C.), spread the concept of coinage throughout the lands he conquered. For both Philip II and Alexander silver coins became an essential way of paying their armies and meeting other military expenses. They also used coins to make a realistic portrait of the ruler of the country. The Romans also used silver coins to pay their legions. These coins were used for most daily transactions by administrators and traders throughout the empire.

Roman silver coins also served as an important means of political propaganda, extolling the virtues of Rome and her emperors, and continued in the Greek tradition of realistic portraiture. As well, many public works and architectural achievements were also depicted (among them the Coliseum, the Circus Maximus). In addition many important political events were recorded on the coinage. Roman coins depicted the assassination of Julius Caesar, alliances between cities, between emperors, between armies, etc. And many contenders for the throne of Rome are known only through their coinage.

Silver was also widely used as ornamental work and in other metal wares. In ancient cultures, especially in Rome, silver was highly prized for the making of plate ware, household utensils, and ornamental work. The stability of Rome’s economy and currency depended primarily on the output of the silver mines in Spain which they had wrested from the Carthaginians. In fact many historians would say that it was the control of the wealth of these silver mines which enabled Rome to conquer most of the Mediterranean world. When in 55 B.C. the Romans invaded Britain they were quick to discover and exploit the lead-silver deposits there as well.

Only six years later they had established many mines and Britain became another major source of silver for the Roman Empire. It is estimated that by the second century A.D., 10,000 tons of Roman silver coins were in circulation within the empire. That’s about 3½ billion silver coins (at the height of the empire, there were over 400 mints throughout the empire producing coinage). That’s ten times the total amount of silver available to Medieval Europe and the Islamic world combined as of about 800 A.D. Silver later lost its position of dominance to gold, particularly in the chaos following the fall of Rome. Large-scale mining in Spain petered out, and when large-scale silver mining finally resumed four centuries after the fall of Rome, most of the mining activity was in Central Europe.

By the time of the European High Middle Ages, silver once again became the principal material used for metal artwork. Huge quantities of silver from the New World also encouraged eager buyers in Europe, and enabled the Spanish to become major players in the late Medieval and Renaissance periods. Unlike the ores in Europe which required laborious extraction and refining methods to result in pure silver, solid silver was frequently found as placer deposits in stream beds in Spain’s “New World” colonies, reportedly in some instances solid slabs weighing as much as 2,500 pounds. Prior to the discovery of massive silver deposits in the New World, silver had been valued during the Middle Ages at about 10%-15% of the value of gold.

In 15th century the price of silver is estimated to have been around $1200 per ounce, based on 2010 dollars. The discovery of massive silver deposits in the New World during the succeeding centuries has caused the price to diminish greatly, falling to only 1-2% of the value of gold. The art of silver work flourished in the Renaissance, finding expression in virtually every imaginable form. Silver was often plated with gold and other decorative materials. Although silver sheets had been used to overlay wood and other metals since ancient Greece, an 18th-century technique of fusing thin silver sheets to copper brought silver goods called Sheffield plate within the reach of most people.

At the same time the use of silver in jewelry making had also started gaining popularity in the 17th century. It was often as support in settings for diamonds and other transparent precious stones, in order to encourage the reflection of light. Silver continued to gain in popularity throughout the 18th and 19th centuries, and by the 20th century competed with gold as the principal metal used in the manufacture of jewelry. Silver has the highest thermal and electrical conductivity of any metal, and one of the highest optical reflectivity values. It has a brilliant metallic luster, is very ductile and malleable, only slightly harder than gold, and is easily worked and polished.

When used in jewelry, silver is commonly alloyed to include 7.5% copper, known as “sterling silver”, to increase the hardness and reduce the melting temperature. Silver jewelry may be plated with 99.9% pure ‘Fine Silver’ to increase the shine when polished. It may also be plated with rhodium to prevent tarnish. Virtually all gold, with the exception of 24 carat gold, includes silver. Most gold alloys are primarily composed of only gold and silver. Throughout the history of the ancient world, gemstones were believed capable of curing illness, possessed of valuable metaphysical properties, and to provide protection. Found in Egypt dated 1500 B. C., the "Papyrus Ebers" offered one of most complete therapeutic manuscripts containing prescriptions using gemstones and minerals.

Gemstones were not only valued for their medicinal and protective properties, but also for educational and spiritual enhancement. Precious minerals were likewise considered to have medicinal and “magical” properties in the ancient world. In its pure form silver is non toxic, and when mixed with other elements is used in a wide variety of medicines. Silver ions and silver compounds show a toxic effect on some bacteria, viruses, algae and fungi. Silver was widely used before the advent of antibiotics to prevent and treat infections, silver nitrate being the prevalent form. Silver Iodide was used in babies' eyes upon birth to prevent blinding as the result of bacterial contamination.

Silver is still widely used in topical gels and impregnated into bandages because of its wide-spectrum antimicrobial activity. The recorded use of silver to prevent infection dates to ancient Greece and Rome. Hippocrates, the ancient (5th century B.C.) Greek "father of medicine" wrote that silver had beneficial healing and anti-disease properties. The ancient Phoenicians stored water, wine, and vinegar in silver bottles to prevent spoiling. These uses were “rediscovered” in the Middle Ages, when silver was used for several purposes; such as to disinfect water and food during storage, and also for the treatment of burns and wounds as a wound dressing.

The ingestion of colloidal silver was also believed to help restore the body's “electromagnetic balance” to a state of equilibrium, and it was believed to detoxify the liver and spleen. In the 19th century sailors on long ocean voyages would put silver coins in barrels of water and wine to keep the liquid potable. Silver (and gold) foil is also used through the world as a food decoration. Traditional Indian dishes sometimes include the use of decorative silver foil, and in various cultures silver dragée (silver coated sugar balls) are used to decorate cakes, cookies, and other dessert items.

ABOUT US: Prior to our retirement we used to travel to Eastern Europe and Central Asia several times a year seeking antique gemstones and jewelry from the globe’s most prolific gemstone producing and cutting centers. Most of the items we offer came from acquisitions we made in Eastern Europe, India, and from the Levant (Eastern Mediterranean/Near East) during these years from various institutions and dealers. Much of what we generate on Etsy, Amazon and goes to support worthy institutions in Europe and Asia connected with Anthropology and Archaeology. Though we have a collection of ancient coins numbering in the tens of thousands, our primary interests are ancient/antique jewelry and gemstones, a reflection of our academic backgrounds.

Though perhaps difficult to find in the USA, in Eastern Europe and Central Asia antique gemstones are commonly dismounted from old, broken settings – the gold reused – the gemstones recut and reset. Before these gorgeous antique gemstones are recut, we try to acquire the best of them in their original, antique, hand-finished state – most of them originally crafted a century or more ago. We believe that the work created by these long-gone master artisans is worth protecting and preserving rather than destroying this heritage of antique gemstones by recutting the original work out of existence. That by preserving their work, in a sense, we are preserving their lives and the legacy they left for modern times. Far better to appreciate their craft than to destroy it with modern cutting.

Not everyone agrees – fully 95% or more of the antique gemstones which come into these marketplaces are recut, and the heritage of the past lost. But if you agree with us that the past is worth protecting, and that past lives and the produce of those lives still matters today, consider buying an antique, hand cut, natural gemstone rather than one of the mass-produced machine cut (often synthetic or “lab produced”) gemstones which dominate the market today. We can set most any antique gemstone you purchase from us in your choice of styles and metals ranging from rings to pendants to earrings and bracelets; in sterling silver, 14kt solid gold, and 14kt gold fill. When you purchase from us, you can count on quick shipping and careful, secure packaging. We would be happy to provide you with a certificate/guarantee of authenticity for any item you purchase from us. There is a $3 fee for mailing under separate cover. I will always respond to every inquiry whether via email or message, so please feel free to write.
