Danburite and Datolite
Dalnegorsk, Kavalerovo Mining District
3.4 x 2.1 x 1.8 CM (miniature)
new year 2021
Gemmy light blue Datolite crystals clustered on a gemmy colorless Danburite crystal. The Danburite has some small etched zones that show re-crystallization, but overall this is a sharp prism. From Dalnegorsk, this is a choice miniature of these two species that looks fine from practically any angle. Our background for this specimen does not specify which part of the mining complex was the source for this piece but it seems certain to be from the Bor Pit. No damage; esthetic and unusual.
A fine, well crystalized old Danburite from Russell, New York. A classic of the Historic St. Lawrence County region, this specimen is from the late Ingeborg Burggraf collection. Several zones on the matrix host dense clusters of Danburite crystals with several habits, most being transparent to translucent and fairly glassy. The crystals reach over 1.3 CM though the majority are smaller. Uncommon on the market, the clear type like this are usually somewhat smaller in size this is well above average for quality.
