This beautiful artificially Coloured Calcite Geode - Black Rock - Turquoise / 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, and the result of a very long process of crystallization. 
Geodes can be difficult to find, as they are difficult to recognize on the outside and are lighter than solid stones.
They are perfect as decorative objects, for example to collect them and display them open. 
NB: Geodes and crystals inside them are painted.
The average size is 8.5x6 cm and might vary as it is a natural product.
