Massive Calcite of beautiful green color.
Calcite appears in a multitude of colors and its coloration depends on various impurities.
The green calcite originates from solutions that contain calcium in their composition. It is found in large hydrothermal veins, but most commonly forms through sedimentation. Their colors are due to natural ionizing radiation.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
