Beautiful example of this rare form of gemstone, found primarily in Mexico. Large, clean stone with good color. You won't find a nicer example, expecially at this price. Natural and untreated. Most gems sold online aren't jewelry grade. They're either poorly cut, have weak color or too many inclusions, giving them the designation collector grade. Collector grade gems aren't worth nearly as much as jewelry grade. This gem is a cut above. We encourage you to do some searches are compare the quality of our gems to others online. The difference should be clear. For Proxibid bidders, shipping is a flat rate of $6, no matter how many lots won.
