Independent documentation

IGI or GIA.
Confidence, documented.

Every diamond we supply weighing 1.00 carat or more individually—whether lab-grown or natural—comes with its own IGI or GIA certificate (grading report).

One report for each qualifying diamond

The 1.00-carat threshold applies to each individual diamond, not a piece's combined total carat weight. Smaller diamonds are not promised individual reports unless expressly stated in your order specifications.

For example, a pair of earrings containing two 1.00-carat diamonds comes with an individual report for each diamond. A piece containing several smaller diamonds does not qualify for individual reports simply because their combined weight reaches 1.00 carat.

What your documentation tells you

IGI—the International Gemological Institute—and GIA—the Gemological Institute of America—provide independent diamond documentation. The applicable report identifies the stone and records its assessed characteristics. Report formats and terminology differ by laboratory, diamond origin, and report type; your selected stone's actual report is the reference for its documented information.

Your order specifications distinguish lab-grown from natural diamonds. The report is evidence of the laboratory's assessment, not an appraisal or a guarantee of resale value.

A report number you can verify

Use the unique report number to look up your diamond directly with the issuing laboratory. Check that the report's details correspond to the diamond described in your order.

Understanding laser inscriptions

Where a laser inscription is recorded on the report, it provides another way to identify the stone under magnification. It is placed on the girdle—the diamond's thin outer edge—and is not meant to be read with the unaided eye. Ask our concierge to explain the inscription and report information for your selected diamond.

Included with your jewelry

We confirm the applicable individual reports for the qualifying diamonds we supply and include that documentation with your order. For bespoke jewelry, you also approve the final design before production begins. Questions about a particular report or a smaller diamond? We will explain what documentation is included before you commit.
