Description

This material was always very rare, caused by the political and geological circumstances there was never much material on the common market. This crystal shows wonderful pink to almost red color with a sharp, intense green cap. The faces are all glossy and the crystals shows very attractive modifications at the end-point. This intensity of colors is very uncommon for the locality, also translucency is amazingly fine - it doesn´t need any back-light to expose these amazing colors! No significant damages to report, bottom was on the rock.
