CERTIFICATE READING
How to read a diamond certificate
Each diamond is accompanied by a certificate issued by an independent laboratory.
This document details the essential information of the stone: weight, color, clarity, and cut quality.
Reading it correctly allows for a methodical, clear, and precise understanding of the diamond's true value.
01
Number
The certificate number is the unique identifier of the stone. It allows you to verify its authenticity and ensure its traceability with the laboratory.
02
Karat
Carat indicates the exact weight of the diamond. It influences its visual presence but should always be considered in conjunction with the other quality criteria.
03
Color
Color is graded on a scale from D to Z. The higher the grade, the purer, brighter, and more visually transparent the diamond appears.
04
Purity
Clarity assesses the presence of internal inclusions and surface imperfections. High clarity means a rarer and visually cleaner stone.
FUNDAMENTALS
The four criteria for excellence
Carat, cut, clarity, and color are the essential benchmarks for assessing a diamond's presence, balance, and quality.
