“ We are very proud to exclusively grade natural and untreated diamonds ”Jonathan Kendall - President, De Beers Group Industry Services
Our laboratories make use of market leading instruments and proprietary technology to support our grading and provide the most accurate and consistent diamond appraisals.
We ensure the integrity of all our processes by using a 'black box' system where diamonds are distributed in anonymous boxes so that each diamond is appraised fairly according only to its features.
We employ some of the world's most experienced graders, who undergo rigorous training, so that they have the knowledge and expertise to evaluate every diamond accurately and consistently, wherever it was mined.

We have transparent published standards for colour, clarity and cut grade for polished diamonds to ensure our grading is accurate and consistent throughout the process. The technology we use, developed by De Beers Group, provides support in areas of treatment detection as well as proportion and colour grading.
A grading report is a vital record of the features of a diamond that make it unique and ultimately determine its value. Our report check enables you to be assured of the authenticity of the grading.
