Hi there, I am selling this really gorgeous yellow zincite specimen. This is a real gem! This particular specimen is from Poland. It is formed as a by product of smelting zinc in this one mine in Poland, that has now since been closed, so no more will ever come from there. The only other place that has zincite is New Jersey and the crystals are as small as dust, they can not be seen with out a microscope. So this location will be the only zincite with crystals large enough to see. If you have any questions, do not hesitate to ask me. Have fun bidding, thanks so much for visiting my auction and have a great day!.
