What is a Veralume Diamond Report?

arrow-down icon
A VeraLume™ Diamond Report gives you a transparent, in-depth look at your diamond’s quality. Each stone is evaluated to the world’s highest standards and includes advanced criteria—like Color Tone, Growth Lines, and Visual Performance—for a more complete picture of beauty and precision.

How do I interpret my grading report?

arrow-down icon
Your report breaks down how your diamond performs in every area—Cut, Color, Clarity, and the added VeraLume™ metrics. Visual Performance measures sparkle and light return, while Color Tone and Growth Lines reveal details that standard reports often miss.

What is visual performance grading?

arrow-down icon
Visual Performance measures how a diamond captures and reflects light—its sparkle, fire, and overall face-up beauty. Each stone receives a score based on precision, symmetry, and light behavior, showing how brilliant it truly appears in real life.

How does VeraLume grade color?

arrow-down icon
VeraLume™ uses the world’s most precise color standards and also evaluates Color Tone—revealing subtle undertones of brown, gray, or blue that traditional reports can overlook. It’s a truer, more transparent reflection of how your diamond looks in person.

How does VeraLume grade clarity?

arrow-down icon
Each diamond’s clarity is graded with top-tier precision and further reviewed for Growth Lines—the natural internal patterns formed during creation that can affect transparency and sparkle. This gives a clearer understanding of your diamond’s overall visual purity.
