Green Calcite Rough Stones (smaller sizes)
Premium-grade green calcite rough stones from Mexico.
Calcite is a common mineral found in most geological environments. It's very soft and can be transparent to opaque. In its purest form, calcite is white or colourless, but impurities in its crystal structure cause a wide variety of colours.
Green typically comes from copper, but it can also come from impurities of iron, but that's relatively rare.
The specific shade of green can vary depending on the concentration of the impurity.
Calcite is allochromatic, meaning its colour is always caused by something outside of its natural chemical elements.
These green calcite stones have been coated with a fine, colourless resin which offers some protection against flaking and crumbling.
Do not submerge in water.
These smaller-sized, rough green calcite stones are being sold by weight.
