Beautiful thumbnail - small black colored Enargite crystals 0,5 – 1 mm in length with a very brilliant metallic luster in a small cavity in combination with some micro pyrite crystals and, possible, white barite. You need some magnification - the pictures are made with a canon maco-lens.

From a old German collection; recently cut from a much bigger piece matrix. Small specimen 50x45x15 mm.
Enargite occurred in large masses with massive pyrite in de Mogul district and was the chief copper mineral of the morning star and other neighboring mines.
