Specimen# CO712B173

Hambergite (gemmy twinned crystal) Arsenopyrite occasionally some fine quality CassiteriteI obtained this piece from Bill Larson, who purchased the specimen in Mogok nearly 20 years ago, and it was a part of my private collection for years. It is one of the largest Hambergite crystals I've seen from the Palelni Mine, even though it's not a complete crystal. It reminds me of similar Hambergites from Afghanistan with the thick blocky form and distinct twinning on the {110} faces. The piece ranges from white and virtually opaque to colorless
