Color shifting! Green to red! 1.73ct VS collectors Tourmaline!

Everyone loves tourmaline, but this example is special. It has a gorgeous yellowish green hue, but when exposed to sunlight under a chelsea filter, this natural gemstone exhibits a rich red body color. A true collectors double threat! This piece measures 8mm x 5.3mm x 4.4mm, and has a fantastic scissor cut and superior luster. Even without the shift in color, this is a stunning gemstone. Sourced from Tanzania. Untreated!
