The bladed crystals are highly lustrous and they are showing and intense mint green to blue colour. Such items are still history and consequently exceeding difficult to purchase.

Copper mineralisation occurs in a belt 4 km long and 11.5 km wide of N-S direction between Panským diel hill and Staré Hory village. (mindat)
