Helping You Find the Perfect Diamond For Your Precious Moments Since 1969

At Washington Diamond, we are committed to helping you find the perfect diamond for your precious moments.

From our online resources to our one-on-one consultations, we are here to help you. Every diamond we own has been handpicked by our diamond specialists and is certified only by GIA, so you can be sure it’s a quality gem.

Each diamond we present is loose so that you can closely inspect the gem before buying and it makes it very easy to compare them side by side.

Our diamond specialists will educate you on how each certified diamond you select is assessed, graded, and priced, so you know you are getting the outstanding value and the right one for you.

Once you pick your diamond, you can choose from hundreds of settings we already stock, or create the setting of your dreams right here in our studio by our experienced in-house goldsmiths. Every single purchase including custom work is risk-free and protected by our 100% money-back guarantee.

The only way to buy a diamond is to come in and see it for yourself. Schedule your one-on-one, no pressure consultation with a diamond specialist today.
