Item Description

PLEASE NOTE: When these specimens first hit the market, they were initially reported and labeled as coming from the Mpita Mine. We have confirmation now that that they are actually from the Ntola Mine. This piece dates back to a find in January of 2019, and features and features beautifu, little groups of very sharp, lustrous, gemmy rich emerald green trigonal Dioptase crystals sitting on silvery rhombic Calcite matrix. Also, upon close inspections there are a few spots of small brilliant orange Mimetite crystals that can be seen. For the most part, the piece is in good shape, with only a few small areas of damage. I had a lot of fun looking at this piece under the microscope. The beautiful formation of the Dioptase along with the fact that Dioptase prices are on the rise makes this a very desirable and eye-catching specimen from this exciting locality in Republic on Congo. Most collectors love Dioptase, but there aren't that many world localities that produce excellent specimens. We all know that the prices for Tsumeb Dioptase specimens are on the rise, but you can pick up this attractive "Tsumeb-esque" specimen for a great price, with an association that is rarely seen around the world.
