Native Copper, 2 Extra Large Twinned Crystals. Caledonia Mine, Michigan. :
$500.00
This display specimen features two extra-large twinned crystals from the Caledonia Mine in Michigan, United States. If you look closely at the pictures and video you can see a clear and defining meeting point of these extra large copper crystals. Not sure if this is more like a contact twin but could possibly even be spinel twinning as it does look at least to myself that the crystals are oriented opposite or 180 ° to each other. This is a large cabinet specimen and is hefty at over a pound! Besides the large crystals it has some different minor crystalization that tend to be cubic/ octahedral in nature. Also has some remnants of quartz and epidote as well but not much. A truly incredible specimen.
