Dioptase with Mimetite (beautiful combo!) (2019 find)

Item Description

From a fine in January of 2019, here is a great miniature from the now well-known Mpita Mine located on the railroad between Lutete and Mindouli in Republic of the Congo (Brazzaville). Dioptase is almost universally loved, but one problem with the species is that there aren't too many world localities that produce excellent specimens. The pieces came to us from a good friend who collected everything personally. These new specimens are honestly a bit different from most of the pieces that we've handled from this locality in the past. Instead of large individual crystals, you can see smaller beautiful clusters of Dioptase on matrix. The color of the crystals shows that classic emerald green hue, and they are highly lustrous with prismatic trigonal form, but what really sets them off is the many small brilliant orange-yellow crystals of Mimetite (confirmed by analysis) underneath. We took some micro photos with a Canon MP-E 65 mm macro lens to better illustrate the quality of the little Mimetite and you can see that they are actually pyramidal in habit, which is not common in our experience. The contrast between the Dioptase and the Mimetites is wonderful, and reminds me in a way of the classic specimens from Tiger, Arizona. PLEASE NOTE: We've listed some of these pieces i the past as Dioptase with WULFENITE, which was also confirmed by analysis, and it appears that both species are present at this locality. The piece is in very good shape and it's a lot fun to view under the microscope. We all know that the prices for Tsumeb Dioptase specimens are on the rise, but you can pick up this attractive specimen for a great price, with an association that is rarely seen around the world.
