Guides to diamond grading reports, certificate verification, laser inscriptions, traceability, and transparency.
Reading a lab-grown diamond certificate can feel like decoding a mix of familiar terms and hidden traps.

When you buy a lab-grown diamond online, the stone and its grading report arrive separately, and trusting that they belong together is the core problem.

When you buy a lab-grown diamond, the most important number isn’t the price — it’s the report number.

An IGI report is the most common document you will see when shopping for a lab-grown diamond, but it can be misleading if you do not look beyond the headline grades.
