Certificates

Documentation for confidence and clarity.

Certificate availability depends on the piece, the diamonds used, and the type of setting. This page explains the current guidance.

International Gemological Institute certificate mark

Selected certified diamonds

Some pieces include an independent diamond certificate depending on stone size, type, and design.

Jewellery-level assurance

For pave designs or multiple smaller stones, documentation may describe jewellery quality rather than each individual diamond.

Product-page priority

The specific certificate or document included with a piece should be stated on the product page whenever available.

Check details

Ask about a specific piece.

Send the product name or order details and client services can confirm what documentation is expected.
