Description

Usually we know golden Chalkopyrite in combination with Siderite from the locality. The Chalkopyrite from this recent discovery shows very colorful iridiscent layer. Both minerals are well crystalized, sharp terminated and highly lustrous. Quality is very good and the contrast just breath-taking. Set in the centre we can see an exposed main crystal which is 22 mm across.
