by pokerface » Apr 24, 2019 Listed as a flawless, 1.37ct tanzanite with traditional heat only. I love everything about it: color, cut and clarity! This will be my first "real" tanzanite; I have two smaller pieces that are pretty ugly, but unheated/untreated. I was inspired by @TheGarnetGirl's recent tanzanite score, and hopefully my little beauty will measure up! Still on my bucket list: a bicolor tanzanite.
