Calcite sand crystalsYour model is disabled. For more details go to Edit properties3D Model
This cluster of calcite crystals are also known as “sand crystals” because of the abundant sand grains that are found within these formations. Calcite (calcium carbonate) is a common rock forming mineral that can act as a cement, gluing sand grains together to form solid rock. It is highly unusual for this cementation process to produce outstanding crystal forms like this.
