Don’t Be Fooled by Bad Certificates
At CDI we pride ourselves in only offering the most accurate diamond certificates available in the industry. The location of the inclusions plays a major role in the overall appearance of a diamond as well as the price.

Viewing Your Diamond:
Unlike most jewelry stores that are hesitant to show you the color and quality of their loose diamonds under magnification, CDI shows you the color in a specifically designed card used by the laboratories for grading color and allows you to view the diamond quality using a state-of-the-art diamond viewer. The location of the inclusions also plays a major role in the overall price and appearance of the diamond, so we make it a priority to educate you on all aspects of the stone.
Diamond Facts
The 4 C’s of Diamonds

COLOR
The color scale below illustrates the various degrees of diamond color. The absolute finest white diamond carries a “D” color grade. When comparing different color grades, most people will be unable to see a difference in color, although there can be a significant difference in price.

CLARITY
The clarity grade is the degree to which the diamond is free of inclusions and blemishes. Most diamonds have internal inclusions, which determines the clarity grade. All certified diamonds are graded under 10X magnification, by trained diamond graders, based on the number, size, and location of the inclusions.

CARAT
Diamonds are weighed in carats, abbreviated “ct.” A carat has 100 points. When you see a diamond weight of 1.15ct, that means one carat and 15 points.
