Diamond Grade Reporting

 

The brilliance (cut) of a diamond influences the diamonds value and price by as much as 25%. Yet is it the least documented or understood when purchasing a diamond.

At Diamond Design Company, prior to mounting we grade each diamond's cut on a Sarin Diamension proportion grading machine. Learn more about the importance of diamond cut.

The Sarin DiaMension proportion analyzer provides the most accurate evaluation of diamond proportion measurements available today. It is used by GIA, American Gem Society (AGS) and other gemological laboratories to analyze diamond proportions.

A trained jeweler should be able to provide a detailed analysis of a diamond's cut grade using a Sarin Report to describe each angle and degree that comprises a well cut diamond.

If a merchant selling diamonds cannot provide you with a Sarin report then BUYER BEWARE!
