Description

A marvellous piece! Several sharp terminated, highly lustrous apatite crystals (up to 29mm across) formed an exposed group, set on matrix! The crystals show a dark violet sharp terminated zoning in their centers, framed by a light outer zoning - this kind of apatite is very rare! The crystal to the left hand side shows a small contacted area at the upper left corner. A very aesthetic, remarkable and uncommon specimen!
