Description

What an impressive crystal! It shows dark blue-green color with a sharp pink zoning at the base and a yellow-green cap. The end-points are consisting of tiny sharp steps, the faces are very glossy. The crystal shows repairs. Bottom was on the rock. The translucency is excellent - it doesn´t need backlight to expose these colors - even the pink zoning at the bottom is good visible only if you place the crystal on light background. A very colorful piece from this famous locality in a very impressive dimension!
