Uvite: A rare and fascinating mineral from the tourmaline group

Uvite is a rare and remarkable mineral that is part of the tourmaline group. Unlike the usual elongated crystals characteristic of tourmaline, uvite often forms short prismatic crystals that almost resemble a garnet. In this article, we take a closer look at the unique properties and history of uvite.

Characteristics of uvite

Although uvite is reminiscent of garnet in shape, the crystals exhibit a threefold symmetry, meaning they belong to the trigonal crystal system. Uvite can be found in various colors, including green, brown and red, and has a hardness of 7 ½ on the Mohs scale.

Many other green minerals, such as uvarovite, demantoïd, vesuvianite, titanite, epidote, emerald, libethenite, ludlamite and (chromium) diopside, may look similar to uvite at first glance, but all have different crystal shapes and often different hues.

The origin and naming of uvite

Uvite is named after the Uva province in Sri Lanka, where the mineral was first discovered. However, there has been some confusion over the naming of uvite. In 2011, the official name was established by the International Mineralogical Association (IMA) as uvite. In 2018, the name was withdrawn again because the type locality material might be a new variant. Finally, the name uvite was re-approved in 2020, with the type locality located on Elba, Italy.

However, most specimens historically considered to be uvite are actually fluor-uvite, which forms a series with uvite. Therefore, without analysis, a “uvite” should actually be described as a mineral from the fluor-uvite-uvite series.

Uvite is a rare and intriguing mineral from the tourmaline group, distinguished by its unique crystal shape and colors. Although it can easily be confused with other green minerals, the threefold symmetry and unusual shape of uvite is unmistakable. Whether you choose to call it fluor-uvite or uvite, this fascinating mineral remains a special asset for mineral and gemstone lovers.

The rarity and beauty of uvite make it a desirable collectible for connoisseurs and scientists. Although its naming and classification have caused some confusion, interest in this unique mineral has remained undiminished. If you are looking for a special specimen to add to your collection, uvite is certainly a mineral to consider.
