Really interesting piece: Several small Calcite crystals dusted with microcrystalline Quartz deposited on a plate of Amethyst Quartz crystals, also dusted with microcrystalline Quartz. This makes for incredible luster, great contrast and an unusual yet intriguing, eye-catching piece – I have yet to see another one like it. A very large specimen in excellent condition.
