Massive green Calcite.
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.
