Thankfully DBOF has gone the extra step of providing BrillianceScope reports for their gems. While its not a perfect system I would consider it a valuable tool for painting a better picture of a stone that may be hundreds of miles away locked in some vault. Even with return guarantees, you may be paying $50 for your Insured FedEx return. This is an expensive way to window shop!
DBOF was helpful in determining the best options for me and I ended up with a beautiful stone that knocks the socks off of anything I’ve seen locally in the same price range.
