Without Aragonite, many of Earth’s organisms would struggle to survive. It is a mineral used by most invertebrates to build their shells and other hard structures. If you've ever admired a colorful seashell, you've indirectly appreciated Aragonite's range of colors and its easy formation at Earth’s surface. Aragonite and calcite share the same chemical formula but differ slightly in their crystal structures, making them polymorphs. They often occur together and look very similar, so distinguishing them usually matters only to geologists. While calcite is more stable and common today, there have been times in Earth’s history when aragonite was more dominant. Both minerals have nearly identical physical traits, showcasing nature’s subtle variations.

Calcite, a prominent calcium carbonate mineral with a hardness of 3, displays a wide variety of forms and colors worldwide. It predominantly consists of marble and limestone. Yellow Calcite, usually seen in solid masses rather than crystals, is especially spectacular from Mexico. Add a touch of earthy brilliance to your collection with this mineral.

The name calcite comes from the Greek word “chalix,” meaning lime. It appears in many colors, including red, green, orange, yellow, blue, pink, clear, black, and white. As one of Earth's most common minerals, it forms the foundation of limestone and marble. It exists in many forms and develops in various geological settings. Some calcite varieties fluoresce blue or red under UV light. It has been used to produce cement and mortar, and transparent calcite has been used to make gun sights and polarizing microscopes.
