Fluor-uvite - Uvite Series (Tourmaline) (large crystal)

Item Description

These crystals were originally identified as Uvite, which is an rare/uncommon Tourmaline species, but they are now classified as part of the Fluor-uvite - Uvite series. Unfortunately, the species are not distinguished visually, so you can only label them as the entire series. 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 miniature sized piece features a very good sized, sharp, blocky, trigonal crystal of a dark golden-green color with high luster, associated with minor Magnesite. Unfortunately there is a notable bit of damage on the corner where the pyramidal faces meet the prism, so the piece is not pristine, but it's still one of the larger "Uvites" I've seen from the locality. From the collection of Vasco Trancoso, a medical doctor and prominent mineral collector from near Lisbon, Portugal (https://www.mindat.org/user-11954.html). He assembled his mineral collection over the course of 60 years, and built a fine worldwide display collection that we recently purchased.
