What's My Diamond Worth?

It’s hard to know what a diamond is really “worth”. We all know how much it costs, but a diamond’s market worth is more complicated to determine, especially when it comes time to resell it. See below for some of the basics in diamond evaluation.

Get Started

Carat weight

This is the most basic and familiar aspect of diamond value, referring to the weight of the diamond. 1 carat = .2 grams.

Color grade

Color grades are based on being completely void of color (D) or having a yellow tone (Z). Fancy colored diamonds have a color scale of their own from ‘faint’ to ‘fancy deep’.

Cut grade

A diamond’s cut quality is based on the difference between the thickest and thinnest points on a scale and how light is distributed throughout the stone. Grading scale: Fair - Excellent.

Clarity grade

Based on the presence or absence of internal flaws, a diamond without blemishes is “internally flawless (IF)” while a diamond with visible inclusions is marked as “I1”.

The Importance of Grading

When re-selling or insuring a diamond, it is in your best interest to have a diamond grading report from a reputable lab. The Gemological Institute of America is the industry’s leading lab, setting diamond grading standards worldwide. A diamond that is GIA-graded can typically demand higher market prices.
