Collectible minerals - full range in stock "Okenite"

Okenite is a mineral that has an unusual appearance. It is characterized by fluffy white spherulites. The length of the edge, sticking out in all directions, can reach several centimeters. The mineral is soft to the touch, but can be wrinkled if handled carelessly. Usually this mineral is found in voids - geodes and tonsils.
You can see okenite stone for sale and buy it in the Minerals of Russia online store.
