The last of the best specimens of emerald green sphalerite (cleophane). This color appears just once in 30 years history of Androvo mine in Erma Reka. It was a small cavity with just several kilograms of excellent transparent sphalerite crystals with deep emerald color. The material was perfect for faceting and at the moment just several hundred grams left. So far this is the only described deposit with this color. There were just few mineral specimens and I have a luck to own more of them, so this is the last small specimen from that cavity. Sphalerite is developed on the top of galena crystal.
