Calcite Crystal Minerals
Calcite is commonly found in limestone deposits, but may also appear in volcanic or mantle-derived rocks. It is a frequent deposit in the stalactites and stalagmites found in limestone caverns, and can also occur as a vein mineral in other specimens. We offer a unique selection of calcite crystals for sale, perfect for collectors, educators, and enthusiasts.
Calcite is a carbonate mineral that gets its name from the German word “Calcit,” derived from the Latin “Calx,” meaning lime. With a hardness of 3, calcite is easily dissolved in most forms of acid. Some translucent, banded varieties of calcite are even referred to as “Alabaster” by geologists.
Calcite can be phosphorescent—meaning it may glow in the dark after being charged with light. This property, related to fluorescence, shows calcite’s ability to store light energy. Its uses span across military, agricultural, artistic, construction, and even toy industries.
FAQs
Q: Where is calcite commonly found?
A: Most commonly, calcite is found in formations of limestone, volcanic rocks, and cave formations such as stalactites and stalagmites.
Q: What is the origin of the name “calcite”?
A: It comes from the German term "Calcit," which derives from the Latin "Calx," meaning lime.
Q: Is calcite a hard mineral?
A: With a Mohs hardness scale measuring 3, calcite is fairly soft.
Q: What makes calcite phosphorescent?
A: Calcite can glow in the dark after being exposed to light due to its ability to store light energy.
Q: What are calcite crystals used for?
