Chondrodite mineral - You can buy these samples

Chondrodite is a mineral of the humite group, which has the properties of pleochroism. Changes its color from light yellow to brown. In nature, in the form of crystals, it is less common than in the form of aggregates. Aggregates usually shine through at the edges. It is rarely used in jewelry because of its fragility. Used as a collection mineral.

You can see chondrodite stone for sale and buy it in the Minerals of Russia online store.
