I have been so happy with the experience that I have raved about them to everyone I know, and would absolutely recommend Washington Diamond again and again.

Our Diamonds

Our Commitment to Quality

At Washington Diamond, we take immense pride in the quality of our diamonds. Each of our loose diamonds has been hand-selected by our trained and certified diamond experts. While we offer a broad selection of ratings, with prices to match, every diamond is natural, untreated, and graded by the same set of international standards. This assures you that when one of our diamonds catches your eye, you will have full confidence that it’s cut, color, clarity and carat are each confirmed with complete certainty. This commitment to quality enables us to provide superior diamonds at exceptional values.

The GIA Difference

The Gemological Institute of America (GIA) sets the most accurate and verifiable standards for “the 4 C’s” of diamond rating – cut, color, clarity and carat. GIA-graded diamonds are known the world over for the accuracy and consistency of their measurement. No two diamonds are alike, but every GIA-certified diamond is measured by the same rigorous standard. At Washington Diamond, all of our loose diamonds are GIA certified. We only offer the best, because it’s what you deserve.

Experience Our Diamonds Firsthand

As part of your one-on-one consultation, you’ll have a chance to view the our diamonds in person, and examine the “4 C’s” yourself. We’ll present you with a selection of GIA-certified diamonds that meet your price and preferences. We’re committed to providing you with the knowledge, information and variety you need to select a beautiful diamond to adore for years to come.
