Herkimer Diamond Quartz crystal lot of 6, mined by myself from Crystal Grove mine and campground, St Johnsville NY summer of 2025. These are not real diamonds, they are double terminated quartz crystals, 100% natural, and naturally form in the shape of diamonds. And are found in Herkimer County NY, hence the name. Acrylic in last pic is 1x1 inch and does not come with sale.
