Geological Origin & Formation

Calcite (calcium carbonate) is one of the most abundant and diverse minerals on Earth, exhibiting over 800 different crystal forms. This Brazilian calcite specimen has been expertly shaped into an egg form, revealing the mineral's inner beauty and UV-reactive fluorescent properties. Brazil's rich geological landscapes produce some of the world's finest calcite specimens, where hydrothermal fluids deposit calcium carbonate in cavities and fractures over millions of years.

Collector's Value

Fluorescent calcite specimens are especially sought after by mineral collectors for their dramatic response under ultraviolet light, transforming from their natural appearance to vivid glowing colors. This UV-reactive property makes fluorescent calcite a fascinating educational and display piece. The egg shape allows for beautiful light transmission and makes this calcite crystal an excellent conversation starter in any mineral collection.

Display & Care

Calcite has a Mohs hardness of 3, making it relatively soft — handle with care and avoid contact with acidic substances. Display away from harder minerals to prevent scratching. For the best fluorescent display experience, view under a shortwave or longwave UV lamp in a darkened room. Clean gently with a soft dry brush only.

About Calcite

Calcite is a carbonate mineral prized by collectors for its exceptional color range, with several world-class Chinese localities.
