Here is a glassy and gemmy, thumbnail hydroboracite crystal from the Kohnstein Quarry in Germany; the best locality for the species. Although many were found here between 2012-2015, it seems only a very few were gemmy, terminated, and fully formed in this size class. This crystal is 2.3 in length and 1.4 cm in width and is colorless and transparent. The shape, clarity, and complex termination makes pieces like this a level of rarity that can stand next to other gem species and hold its own. In person, this has a high level of refraction with outstanding luster and clarity. From the noted collection of Paul Stahl, a specialist in aesthetic rarities based in Mannheim, who was among the first to be able to buy these once they came to market. This is a significant competition level species thumbnail.
