Calcite Geodes Black Yellow – Crystal 8.5x6cm

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.
