What is Fluor-uvite?
A rare tourmaline found in conjunction with high quantities of boron, fluor-uvite has almost no practical use. It is largely sought by collectors who value it for its scarcity, color and (often) large crystals. Its name derives from Uva Province, Ceylon (now Sri Lanka), where it was first categorized in 1929.
