A large, yellow Calcite Crystal! A really lovely piece of calcite, quite vibrant in colour and with excellent crystal shape. Calcite is a popular stone for its variation in shape and colour, great structure and other properties. This mineral is common and cool at the same time! Looks more yellow in person.

Calcite name is from chalix the Greek word for lime. This is a most amazing yet, common mineral. Comprising about 4% by weight of the Earth’s crust and formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic, fossiliferous and massive limestones in sedimentary environments. Calcite serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events. Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins.
