Calcite – One of the World’s Most Versatile Minerals

Calcite is an abundant and diverse mineral on Earth. It’s used in everything from cement and chalk to toothpaste and sculptures, surrounding us in ways we rarely notice. But practical uses aside, calcite is also a stunning gemstone for jewelry.

This mineral appears in crystal clusters, massive formations, or banded patterns. Some varieties exhibit strong fluorescence under ultraviolet light, while others display optical effects like double refraction, where objects viewed through the crystal appear doubled.

• Special features: Some specimens glow brightly under UV light, while optical calcite (Iceland spar) shows double refraction

Fun fact: “Calcite” comes from the Latin word “calx,” meaning “lime,” because calcite is the main mineral in limestone and quicklime (calcium oxide).
