Fluor-uvite - Uvite Series (Tourmaline) (ex Rolando Gioia Collection)

Item Description

For many years, we labeled all these specimens as Uvite Tourmaline, but it's important to note that these crystals are now defined as being part of the Fluor-uvite - Uvite series, and unfortunately they cannot be distinguished visually. With that said, it appears that most pieces that were labeled previous as Uvite are likely to be Fluor-uvite, but we are labeling these specimens going forward as Fluor-uvite - Uvite series. This large thumbnail sized piece features a few small, tabular, trigonal crystals of a dark green color with high luster and excellent gemminess sitting on colorless to white, very sharp, lustrous gemmy Magnesite crystal matrix. The Fluor-uvite - Uvite crystals measure up to 3 mm, but look beautiful under magnification. A good quality thumbnail of these world-class "Uvite" crystals. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
