Above and Beyond Quality

Beauty may be in the eye of the beholder, but quality should never be a compromised. See the difference well-cut gemstones can make. Most of our larger and higher grade gemstones are American custom cut by me. Even most of the smaller or less-valuable stones are cut by the highest skilled overseas by American-trained cutters using modern equipment because we care so much about quality. No matter what type of gemstone, jewelry, or mineral you're looking for, BVGW guarantees it with a money back or exchange guarantee. See our Terms and Conditions page for more details.
