Calcite Geodes Black Deep Purple – Crystal 8.5x6cm

This beautiful artificially Coloured Calcite Geodes Black Deep Purple, offers its colour once opened, the crystals which formed there are magnificent.

Geodes are hollow stones, inside which crystals have formed. Each geode is therefore absolutely unique, resulting in a very long process of crystallization.

Geodes can be difficult to find, as they are harder to recognize on the outside and lighter than solid stones.

The average size is 8.5×6 cm and might vary as it is a natural product.
