Description

This is an outstanding rarity! The red variety of quarz is the most rare from this famous locality. Most of this specimen are clusters or only on light matrix. Not so here! The crystals are resting on jet-black matrix - the contrast could not be better. The quarz crystals show an alongated habit, the are sharp and glossy. Nearly all these pieces were demaged while extraction, so I have to note that this one is in really good condition. Nearly all of the main crystals do not show any significant demage, only a few less prominent at the backside are broken.
