We are a small business- not professional jewelers- and can keep costs low. These stones are not absolutely perfect, there may be small inclusions, stone may be top heavy, or a slightly odd size but they do not impact their beauty, and they also do not cost thouands of dollars. We always use sterling settings to avoid the high cost of gold. We rely upon the certifications and descriptions bythe few reputable wholesale gemstone vendors we use that the gemstone is naturaly mined. We only select our stones for their beautiful cut and color! The item "Certified RARE Natural 20.20ct Blue Green Parti Sapphire Ring Sterling Size 6" is in sale since Friday, July 23, 2021.
