Item Description

Charcas is a famous Mexican locality, well-known for producing the world's greatest Danburite crystals, along with many other distinctive minerals. The Datolites from this area are some of the best examples of the species ever found, with fine quality crystals and attractive colors. It's one of the few places in the world where blue Danburite has been found, and this piece is a great example of said material. This miniature sized specimens hosts several very sharp, rather lustrous, translucent, light blue colored blocky crystals measuring up to 2.2 cm, free of matrix. A tiny bit of black Sphalerite can be seen on the front/display side of the piece. No major damage I can find, and really showy. A very fine miniature of this now hard to find material dating back to the 1970s-1980s.
From the collection of Colorado mining legend, Dave Bergman. Dave is now retired from mining, but was formerly the foreman and primary person in charge of recovering specimens at the famous Sweet Home Mine near Alma, Colorado during the late 1970s, and the maternal grandfather of Brian Kosnar. See Dave's photo mining at the Sweet Home on page 58 of Peter Bancroft's book "Gem and Crystal Treasures".​
