Beautiful twin with superb habit and very attractive drusy surface. The crystal is so sharp that, if you follow the twinning plane down, there is an extremely attractive little triangular face right at the base of the plane. It is barely visible in the photos because of the lighting angles, but it stands out beautifully in person. Just a contact on the back and one tiny ding, otherwise perfect all over. This is quite the aesthetic thumb and incredible for the species, especially from a US locality.
