What the Certificate Covers

A certificate documents the stone: its identity as a lab grown diamond and the grading criteria reported for it. It is a statement about the stone, not a valuation and not a durability guarantee.

When a Third-Party Report Is Needed

Some markets ask for a report from a recognised laboratory at the point of sale or import. Where that applies, the report is arranged against the stones in the order rather than added later.

Certificate Questions

Do all stones ship with a certificate?
The certificate set follows the order; tell us the market and the point of sale and we will confirm what is required.
Does a certificate state a value?
No — certificates describe the stone, not its price or resale value.
