A diamond grading report is an important tool for diamond sellers because it helps them and potential buyers determine what they have. When it comes time to determine a reserve price for your piece, the diamond grading report will help you and your auction manager figure out the best price to work with. When your auction manager creates the listing, the characteristics and grading report help our buyers buy with confidence, knowing that the information they are getting about the diamond is coming from a trusted, third-party grading lab.
