"A laboratory report is an unbiased assessment of the stone's quality and gives you extra piece of mind so that you can wear your Bradleys diamond with confidence."

Diamond Basics
Certification
Buy With Confidence
The majority of our diamonds over 0.25ct come backed with a Diamond Certificate from an independent laboratory. It acts like a passport which tells you about your diamond's credentials, like its Cut, Colour, Clarity and Carat weight. Due to their exceptional reputation, we primarily use Gemological Institute of America (GIA). The GIA is an international non-profit organisation dedicated to producing consistent, accurate and unbiased grading reports.
Why do we choose GIA?
Strict Quality Control
GIA employs hundreds of highly trained diamond graders, gemologists and research scientists who scrutinize the diamonds and analyze them. So you can rest assured that your GIA graded diamond will have been checked and cross-checked by a number of experts before the report was generated.
Uniquely Inscribed
All GIA graded diamonds have a unique serial number laser inscribed on the girdle which enables you to match the diamond to its certification.
Internationally Recognised
GIA is the industry gold standard in diamond grading. A GIA diamond certificate offers you the best grading and most protection for your special investment. Diamonds graded by the GIA are often the most highly valued and respected in the industry.
Secure & Digitally Logged
Your GIA report will contain security features such as a hologram, security screen and microprint lines that prevent them from being forged or duplicated. On top of this your diamond is digitally logged on the GIA database.
World Class Training
The GIA doesn’t just grade diamonds, it also educates. At Bradleys we are proud to house an amazing talent of GIA Graduate Gemologists, GIA Accredited Jewelry Professionals & GIA Diamond and Pearl graduates.
