GIA Graded Diamonds

Due to their exceptional reputation, we only use Gemological Institute of America (GIA) graded center diamonds.

The GIA is an international non-profit organization dedicated to producing consistent, accurate and unbiased grading reports. Diamonds graded by the GIA are the most highly valued and respected in the industry. Each stone is graded twice, by different graders, to ensure they arrive at the same grading report.

GIA developed their grading system so you can choose a diamond without seeing it, yet still trust you’re getting exactly what you wanted.

A GIA diamond grading report details an appraisal of the 4Cs and is the result of work from a whole team of gemologists. Trained eyes scrutinize the diamond using specific tools and analyse the ratios of the dimensions, clarity, color, polish, symmetry and other elements before determining its grade. Any diamond that weighs over 1.0 carat will be automatically assessed for clarity and rated on a plot chart of inclusions, and round diamonds also include a cut grade on their reports.

All of our diamonds have a unique serial number laser inscribed on the girdle which enables you to match the diamond to its certification.
