Detailed Description

A super display specimen from Brumado! The base main body of the piece is made up of quartz crystals – some are complete, and some seem truncated – close examination shows that the surfaces around the piece all show crystallization patterns (they are not damaged). The beautiful sharp, lustrous glassy green fluor-uvite crystals are perched on the quartz crystals, and clear, colourless magnesite crystals are also associated on the quartz crystals. In excellent condition. This is a great piece – it came out years ago (most specimens one sees were collected in the past).

About Brumado Tourmalines in the Fluor-Uvite – Uvite Series

In this profile, I have labelled these specimens fluor-uvite, with the following explanation. Until the more recent IMA reclassification of the Tourmaline Supergroup, these specimens were known as uvite. It is now impossible to distinguish individual specimens in the fluor-uvite – uvite series without advanced analytical techniques. These techniques have not been applied to these individual specimens. However, The RRUFF Project has confirmed that at least some crystals of this appearance from Brumado are fluor-uvite, and I’m not aware of any analytical work that has confirmed the presence of uvite at Brumado. Uvite is much less common than fluor-uvite. The label which accompanies the specimen says “Fluor-Uvite – Uvite”.
