Barite

Description

The Miraflores mine in the Huallanca district of Ancash, Peru, is one of the world’s classic barite localities, renowned for producing large, tabular to prismatic orthorhombic crystals of exceptional transparency. Miraflores barite ranges from colourless through pale yellow to warm golden, often with a brilliant vitreous to resinous lustre that gives well-crystallised specimens a jewel-like quality.

Barite (barium sulphate, BaSO₄) is the primary ore of barium and is one of the densest common minerals — its notably high specific gravity of around 4.48 is a reliable field test for the species. The combination of large crystal size, clarity, warm colour and high density makes Miraflores barite among the most collectible South American mineral specimens, prized by collectors across Europe and North America.
