“I know my sources for diamonds. I’ve been dealing with them for many years and deal almost exclusively in diamonds accompanied by a grading report. My policy is every diamond I sell that weighs one carat or more comes with a GIA grading report - I’m a stickler for GIA reports. I do a lot of custom work, so I order goods from vendors I know and trust. Typically, I’ll source multiple diamonds for a single customer. We’ll take the time to look at each one under a gemological microscope to teach them about diamonds and to examine each diamond in greater detail and find the diamond the customer likes the most for their custom piece.
