Gorgeous Citrines. Just exceptional stones and well matched. A great set. 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 and compare the quality of these gems to others online. The difference should be clear. You aren't going to find stones like this anywhere else at this price. Easy money maker for the amateur or professional jeweler.
