Green Calcite + Dude Rocks Card

The Green Calcite comes with a Dude Rocks informational card for your son to learn more about the stone. Here is what it says:

Green Calcite is found in numerous locations around the world including the US, China and Mexico. It is formed when calcium carbonate in water collects underground and over time accumulates and solidifies forming solid rocks. Green Calcite gets its color from the chlorite present during the rock formation. Calcite is a major component of limestone, which is used to manufacture concrete.
