What is Calcite?

The calcite crystal is most commonly found in sedimentary rocks, hydrothermal veins and caverns. The process of formation includes rapid dehydration of calcium carbonate that produces vaterite which later turns into Calcite through recrystallization. Other inclusions within the compound result in many varieties of colors. Calcite also grows in TONS of different formations such as bladed, point, tabular and more.

Calcite is a carbonate mineral. It’s a crystal that can easily be scratched by sharper materials because it’s a 3 on the Mohs scale of harness. It has a conchoidal fracture when the mineral breaks. This material is also highly reactive with acids, even with the weaker ones like vinegar.

Calcite’s name was inspired by the Latin word “calx” meaning “lime”. This points out that the mineral is mainly formed in limestones.

Additionally, calcite crystals have long been embraced in metaphysical practices for their unique energetic properties, offering a multifaceted experience for those who explore their fascinating world.

Why some calcite glows under UV

The UV reactivity of calcite crystals is attributed to the presence of certain impurities or trace elements within the crystal lattice. One of the most common causes is the presence of manganese (Mn) ions, as is the case for mangano calcite, which can cause calcite to exhibit a fluorescent or phosphorescent response under ultraviolet light. When exposed to UV radiation, the manganese ions absorb energy and then emit it as visible light, resulting in a vibrant glow or color change in the calcite. Other factors, such as the crystal's structural defects or the presence of rare earth elements, can also contribute to UV reactivity in calcite. It is the unique combination of these factors that gives rise to the fascinating UV-reactive properties observed in some specimens of calcite.
