Deep Blue-Green Fluorite Cubes from Okorusu Mine, Namibia

This impressive Fluorite specimen features a dense cluster of sharply formed cubic crystals displaying rich blue-green tones with subtle hints of purple visible in certain areas. Several prominent cubes dominate the specimen, creating a bold geometric appearance that immediately captures attention. The crystals exhibit excellent transparency around the edges while deeper sections appear darker, producing remarkable depth and contrast. Small remnants of the original matrix and natural mineral coatings accent the crystal cluster, adding authenticity and character to this classic Okorusu Fluorite specimen.

Fluorite forms when mineral-rich hydrothermal fluids circulate through fractures and cavities within host rocks. As these fluids cool, dissolved calcium and fluorine crystallise into the distinctive cubic crystals that make Fluorite one of the most recognisable and sought-after minerals in the world. Trace elements and variations in growth conditions can produce a wide range of colours, with the deep blue-green tones seen in this specimen being particularly desirable among collectors. The sharp crystal faces and strong cubic development make this an excellent example of Fluorite's classic crystal habit.

The Okorusu Mine is one of Africa's most famous Fluorite localities and has produced some of the finest Fluorite specimens ever discovered in Namibia. Formed within a complex carbonatite-related geological system, the mine became renowned for yielding colourful cubic Fluorite crystals displaying remarkable clarity, colour zoning, and aesthetic crystal groupings. Today, Okorusu specimens remain highly prized by collectors worldwide, particularly as material from the locality becomes increasingly difficult to obtain.
