Description

The crystal is almost 45mm tall, it shows an very uncommon habit for Tennantite, the very best luster you can imagine and fantastic texture on all faces. The faces are sharp terminated - more sharp as you can see on my photo, but my mayor intention was to show luster and texture. The crystal is also complete at the reverse, where is developed micro-steps and it is set on a small „base“ od white, sharp Calcite crystals. A really remarkable specimen for Russia and Tennantite in general.
