Color shifting! Chrome green to orange! 1.73ct collectors Tourmaline!

Everyone loves tourmaline, but this example is special. It has a top chrome green hue, which by itself would be spectacular, but when exposed to sunlight under a chelsea filter, its top chrome hue turns rich reddish orange! A true collectors double threat! This piece measures 7mm x 5.5mm x 4mm, and has a fantastic oval cut and superior luster. Even without the shift in color, this is a stunning gemstone. And if you don't have one yet, don't miss this opportunity. Nature's not in any rush to make more. Sourced from Tanzania. Untreated!
