The Four C's of Evaluating Diamonds

A Diamond's Cut Grade

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape, but a diamond’s cut grade is really about how well a diamond’s facets interact with light - crucial to the stone’s final beauty and value.

Colour Grade

GIA's D-to-Z color-grading scale is the industry's most widely accepted grading system. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.

Diamond Carat Weight

Diamond Carat Weight Measures a Diamond’s apparent size. A metric “carat” is defined as 200 milligrams. Each carat is subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place.

Diamond Clarity Grade

Diamond Clarity refers to the absence of inclusions and blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone.
