What GIA Diamond Quality Reports Do Not Tell You:

Certified-Plus Diamonds provides the highest online customer satisfaction rate. Our statistics show that ninety-eight out of every one-hundred Certified-Plus Diamonds delivered meet or exceed customer expectations. This far exceeds the 50% to 75% return rate that is common to many online diamond brokers and dealers.

Why is Certified-Plus Diamond more successful? Only Certified-Plus Diamonds examines and verifies all the important elements of diamond cut. Our Certified Gemologist-Appraisers carefully examine every diamond to ensure that crown height, crown angles, pavilion depth percentage and pavilion angles are within the ranges of ideal to very fine quality before it is shipped to you. Selecting a diamond without the assurance of these important elements is risky and is not advisable.

Certified GIA diamond quality reports provide only the total depth percentage. The total depth percentage alone does not provide enough proportion detail to provide complete assurance that a diamond will have ideal or very fine cut quality. The cut quality of a diamond may vary considerably even when depth proportion is correct.

Selecting A Diamond That Has Total Depth Percentage Within The Recommended Range For Ideal To Very Fine Cut Does Not Guarantee Proper Cut. (See Details Below)

Total depth percentage is very important but it can be misleading. Total depth percentage is a representation of a diamonds overall total depth. As the diagram illustrates, it is possible for two diamonds to have the same depth percentage and be proportioned differently.

Total depth percentage is a  combination of many other important elements of diamond cut. These elements include crown height, crown angle, pavilion depth percentage, pavilion angle and girdle thickness. These elements are  properly proportioned in ideal cut diamonds.

However, some diamonds with total depth percentages that are in the range of ideal may be improperly cut and display less brilliance.  A diamond with ideal total depth percentage may also have an overly deep bottom, (deep pavilion depth percentage & steep pavilion angles) and have a very low top, (low crown height & shallow crown angle.) Another way to understand this is to consider two people which have the same height. One has the ideal physique, the upper body in proper proportion to the lower body. The other person with the same height has very long legs and a short upper torso which is less attractive.

Certified-Plus Diamonds Certified Gemologist -Appraisers carefully examine every diamond to ensure that crown height, crown angles, pavilion depth percentage and pavilion angles are within the ranges of ideal to very fine quality before it is shipped to you.
