Black Rose Cube Fluorite 210 Grams Specimen Excellent Cube Display Fluorescent Black Rose Crystal Mineral Specimen Pakistan #300Locality: Pakistan
Weight: approx. 210.00 Grams
Measures: 2.92\'\' (73.80mm) x 2.52\'\'(64.20mm)x 1.71\'\'(43.44mm)A very RARE AAAA Black Rose Cube Fluorite Fluorescent specimen, sourced from Pakistan.
This is a Phenomenal example of a Black Rose Fluorite specimen that has a pure deep black coloring and exhibits a phenomenal cube cluster display. The distinctive stair tiered cube faces show the classic stepped habit that is a signature characteristic with Cube Fluorite and give this piece depth and quintessence. Having the ability to position this piece in a couple different ways, sets the stage for it\'s magnificent display in daylight...But it\'s fluorescence is where it really shines! Especially notable under LW UV light is the beautiful luminescence this piece exhibits! Not to mention the beautiful complex fluorescent zoning revealed, due to the conflict between the cubic and octahedral systems as the crystal was forming. This specimen is a must have for any fluorescent collection! The contrasting shapes, beautiful cube formations and fluorescence of this crystal group, make this piece a very attractive three dimensional Black Rose Cube Fluorite Mineral Specimen. Black Rose Fluorite is a captivating mineral renowned for its deep and mysterious black cube crystal formation that invokes the mystique of a black rose. The combination of it\'s pure black coloring and deep red \"rose\" fluorescence, suggests the symbolism, that exudes the fascination and allure of this magical Fluorite. However, this stone\'s true wonder is ultimately revealed under Longwave Ultra Violet light (LW UV 365nm). This Black Rose Fluorite bursts into life remitting a vivid display of blue, pink, purple and deep red luminescence.
Black Fluorite is one of the rarest colors to find and why it is so highly sought after.
Such a beautiful amazing piece and very Be aware that being able to view fluorescent minerals requires an ultraviolet (UV) lamp. A LW UV 365nm was used for this specimen. A black light is not a UV light and in most cases fluorescent minerals will not fluoresce with a black light. What makes minerals fluorescent?Ultraviolet light is a form of electromagnetic radiation. Fluorescence occurs when electrons in certain atoms of a crystallized mineral absorb the radiated energy from a UV light (Photons). The incoming photons bump the electrons into higher energy states, and they respond to the ultraviolet light. The remaining light energy is out of balance and remitted and can be seen as a visible color. The reason for the fluorescent remitted colors is due to impurities in the mineral, or activators; which become part of the mineral?s chemistry by taking the place of atoms in the host mineral.
A majority of activators are atoms of certain metal elements that cause the resulting fluorescence in a mineral, Manganese being the most common activator. The level of fluorescence depends on the percentage of the impurities in relationship to the host atoms. Too much/little, results in low or no fluorescent response.Side Note: Fluorite, is also known as Fluorspar, is named for its fluorescence under ultraviolet (LW UV 365nm) and cathode-ray irradiation. Rare-earth elements, transition metal elements ( such as Chromium, Manganese, Iron, and Zinc) and alkaline elements (Sodium or Potassium) aka impurities, can often take the place of atoms in Fluorite basically occupying the crystal lattice structure of Fluorite. Since pure Fluorite is colorless, the existence and specific levels of these impurities determine the color of Fluorite in natural light, but also lead to the fluorescent color and phosphorescence it remits.
>>> Fluorite and surrounding rocks often contain radioactive elements. Therefore, Fluorite can be irradiated naturally before it is mined, not to say that it cannot be treated in a lab! Consequently, it would be unreasonable to suggest, assume or claim that a specimen is specifically treated in a lab, as apposed to natural irradiation, unless the lab actually made the claim.
