Description

Hi! Here are more speciems that i´ve doing out of my collection and that i offer here.

This is a large and very nice speciem with a good parageneses. The main mineral are some nice tabulare black coloured crystals of Wolframite up to 1.5 cm large. In farther parageneses you will find also nice crystals of partly colorfully tarnished Chalcopyrite up to 1 cm diameter and also many Quartz crystals, partly show nice Scepters. At least there are small crystals of Calcite and Sphalerite on the speciem.

It comes from the former collection of A. Gehrlein, Saarland, Germany.

Sorry because of the height and the large of this speciem the shipment outside Germany is expensive. I´ll only ship registered via DHL.
