Cumengeite (Twinned)
Amelia Mine, Boleo, Chihuahua, Mexico
Thumbnail, 1.3 x 1.1 x 1.1 cm
An incredible cumengeite of super high quality, the best I have seen for sale in fact. It has top luster, deep blue color, and extremely good 6-point symmetry. It has one truncated rear termination and the bottom termination point is contacted (but you have to mount it somewhere, anyhow?!). Otherwise, it is complete and pristine. This is an incredible rarity and a chance to own a piece of such high caliber that few outside of the Sorbonne actually possess. One of the finest thumbnails I have had to offer...
