I've been seeing jewelry supposedly made with black zircon. The black zircon comes from Sri Lanka according to what the Sellers say. I've found a few pieces of black zircon loose gemstones on Ebay for sale by Sellers from China for low, low prices but don't trust them. They also say the black zircon is from Sri Lanka. I've asked two top gemstone buyers who travel the world buying gemstones and they both indicate they've never heard of black zircon. On this website, under colors of zircon, you do not list the color black. So has anyone heard of natural, black zircon yet? Thank you.
