The Importance of Credentials:

The most valuable component in selecting a diamond is the service and expert assistance you receive when selecting your diamond. Because G.I.A certified diamond quality reports do not provide you with all the important details you must have to adequately evaluate a diamonds cut quality, having a qualified expert to verify all the aspects of your diamond selection is crucial.

Certified-Plus Diamonds is the home to:
United States Gemological Laboratory and has (2) Two Certified Gemologist-Appraisers who carefully examine and discuss with you the important details of cut, color, clarity before your diamond it is shipped.

Every Certified-Plus Diamond is carefully examined in our A.G.S accredited gemological laboratory before it is considered for shipment to you.

Our Sarin proportion analyzer and the Gran Colorimeter provide important details about the your selected diamond that is not shown on the G.I.A. diamond quality report.

The accurate evaluation of color, clarity and a diamonds cut proportions are essential to the assurance of your diamonds quality.

Few jewelers or online diamond brokers provide you with this high standard of qualified service. Certified-Plus Diamonds delivers to you the comfort of knowing your diamond is carefully examined and evaluated before it is sent to you and that the diamond you selected will meet the high standard of excellence you expect when you receive it. This is the added value you receive from Certified-Plus Diamonds.
