The Prince Mine is located in Mineral County, Nevada near the Candelaria Mining District. This area is famous for its silver and turquoise. Prince Variscite mine produced large veins and nuggets of minty green variscite, both pure color and with intricate to bold spiderweb patterning. Impressive black, orange, and yellow variscite also comes from this mine. Prince Mine was worked quite deep along the vein and then refilled the hole as part of the reclamation work. As a result, the vein has not been mined since 2005, and this wonderful gem is only becoming more and more rare. The Son and I do all the cutting work we never farm it out. We are Native American gem cutters, we are registered members of the federally recognized Native American tribe Wichita Indians out of Oklahoma. To be clear “100% NATURAL” it is all turquoise no backing was used If it just says “NATURAL” it is natural and backed with JB Weld. The photos in this listing are taken in natural sunlight on a white background. I do this because any color background except white can alter the colors in the photo. I realize Direct sunlight and white background is the worst possible conditions to photo in. I would rather have you say it looks so much better in hand then be disappointed when you get the stone. If you would like a photo in shade, just ask.
