Houses have deeds. Vehicles have titles and registration. It only makes sense that you have similar documentation for something as precious as your diamond purchase.
A diamond grading report isn't an appraisal. It is the scientific blueprint of a stone's exact quality characteristics. A GIA Diamond Grading Report is your assurance that your diamond is a natural diamond, with clear disclosure of any treatment to enhance color or clarity. The report provides the kind of clear evidence that is vital to a confident purchase.
