Gem: Nifontovite Stock #: NIFON-001 Weight: 0.1560 ct Size: 6.88 x 1.96 x 1.75 mm Shape: Rectangle Color: Colorless Clarity: Eye clean Origin: Charcas, San Luis Potosi, Mexico Treatment: None (natural) Price: $145.00    [ Make offer ] Pictures are of the actual gem offered for sale. Gem images are magnified to show detail. This rare gem is from the first find of facet grade Nifontovite crystals since Dr. Pough's find in 1940. There were a very limited number of clean crystals found and the majority of them were snatched up by mineral collectors. A very few were obtained for faceting so this one is a true rarity!
