Very pure tourmaline with good color. 1 carat is too small to be worth a lot of money. It's only a few hundred dollars. I specialize in this gem-grade tourmaline. Xidan Street 109 Jewelry Hall, 3rd Floor, Wedding Building, 3073 Jinyuan Tourmaline There are many such small tourmalines. In addition, unlike diamonds, tourmaline has two grades, VS and VVS, both of which are fabricated. As long as it is invisible to the naked eye, there are cracks, inclusions and sponges.
