English: Topaz
Locality: Xanda mine (Xandra mine), Virgem da Lapa, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org)
Size: 9.0 x 8.3 x 7.7 cm.
The Xanda mine is one of the most prolific localities for blue Topaz in the world, and has produced some of the most impressive and memorable specimens with that distinctive preferential etching and larger sized crystals. This specimen is certainly a large Topaz from any locality, not just Brazil, and is in amazingly good condition for the size. The piece has some delicate and graceful hydrothermal etching along the sides of the prism plus the pinacoid, yet has a very well defined, large, selectively etched (041) face displayed prominently at the front of the specimen. Many have one or the other, but not both in quality. There are also some very sharp (un-etched), pyramidal (111) faces at the termination. Overall, this gemmy, baby blue color, sharp, lustrous cabinet size display piece is wonderful Topaz from this most classic of Topaz localities. Rarely do the Topaz crystals from Xanda reach this size without serious etching, which can leave them as nothing more than etched pieces of gem rough, so to find a crystal in this condition is rather rare. Ex. Richard Kosnar Collection.
