Your Diamond,
Independently Certified.
Every Isla Bella diamond is graded and certified by the International Gemological Institute — independently, with no connection to Isla Bella.
One of the world's leading independent diamond grading laboratories.
The International Gemological Institute (IGI) is a globally recognised, independent laboratory that assesses and grades diamonds with no connection to the seller.
When your ring arrives, it comes with a full IGI certificate — a permanent, verifiable record of your diamond's exact quality. This certificate is not issued by Isla Bella. It is issued independently, so you can trust it completely.
Every Isla Bella diamond meets our premium standard — D–F colour, VVS clarity, and Excellent cut — verified and confirmed on your certificate.
How well the diamond returns light — fire, brilliance, and scintillation.
How white the diamond appears — D–F is colourless, the highest grade.
How free the diamond is from internal marks — VVS is exceptional purity.
The exact weight of your diamond, verified and recorded independently.
Verify on the IGI Global Registry.
Once your ring arrives, you can verify your certificate directly on IGI's official website using your unique report number.

This provides a permanent, physical link between your diamond and its certificate.
