Yellowish orange tabular crystals of Nadorite. These are extremely hard crystals to obtain on the market. The best crystal is that of the second photo. It is 1mm and is the type of crystal that is shown on Mindat by Christian Rewitzer. There are several smaller crystals. The white sprays have been identified as Mimetite at the RRUFF lab. The Mimetite was an unkonwn as reported in the book "Langban" by Bollmark and others.

Numerous silvery lead-grey somewhat foliated metallic plates to 7mm. There are SIX large plates from 5 to 7mm with numerous smaller plates throughout the specimen. As is typical of specimens from Nagyag, Rhodochrosite covers much of the crystals. Fortunately on this specimen alot of the crystals were not encrusted over by the Rhodochrosite. Cross twinned lamellae can be seen on the crystals. Nagyagite is a soft mineral (1.5 Mohs) with thin foliations much like Molybdenite.
This mineral gets its name from the type locality at Sacarîmb, also called Nagyág, in Romania. Nagyagite is an uncommon mineral that occurs in epithermal hydrothermal gold and tellurium bearing deposits. It can be found additionally in the Czech Republic, Kazakhstan, Armenia, Zimbabwe, the United States, Canada, Argentina, Australia, New Zealand, Japan, and Fiji among others. Although most other localities rarely surface on the market. Nagyag is the undoubtedly the best and most desirable and sought after. Even on Mindat, there are no other localities photographed. In our MineralPedia, we have the Czech Locality at Kasejovitz photographed.
