Diamond Engagement Rings


we do diamonds differently. So Should you!

Platinum Solitaire Engagement Ring with Half Carat Modern Euro Diamond with Milgrain Band Copy

We are proud to “do diamonds differently.” We offer top-quality diamond rings and loose diamonds presented in a low-pressure environment, where each Diamond is selected for its beauty and value. Most of our diamonds are kept unmounted, such that they can be used in any of our over 250 ring mountings that we have on hand, as the centerpiece in a custom design, or set in a mounting you already own. By keeping our diamonds loose it gives us greater inventory flexibility and keeps our prices low. We always pre-made rings in stock for our clients to try on the hand: classic solitaires, 3- stone, and halo designs, as well as vintage-inspired options. In addition to the wide range of natural certified diamonds we have on-hand, we also stock lab grown diamonds and can source any size, shape

Diamond Brokerage Service

We are proud to offer an exclusive Diamond Brokerage service for clients looking for the perfect Diamond- natural or lab created. This service is aimed at those seeking larger or unusual Diamonds which we would not typically keep in stock. We work with partners around the world to source our Diamonds, which we guarantee to be ethically sourced and beautifully cut. In addition, we are often able to beat our competitors’ prices- even online and big box stores- and deliver the finest quality around, while providing our clients an informed buying experience. 

How does it work?

    1. Meet with our GIA-trained diamond experts to start your Diamond search
    2. Develop a wish list, preferred quality range, and budget that we can target
    3. We search the country for Diamonds matching your criteria, and order a selection for you
    4. Come in to view the Diamonds in person: compare, analyze, and choose
    5. Purchase the Diamond you like best. We always say: follow the sparkle!
    6. Work with a jewelry expert to set your Diamond, in your existing ring, a new ring, or custom design

Are you looking for a natural GIA-certified 2ct cushion cut Diamond that is VS clarity and colorless for your engagement ring?

Feeling Overwhelmed? We Can Help!

If buying a diamond seems daunting, come and see us. Our GIA-trained staff enjoys educating our clients about diamonds– we can give you a basic rundown on the 4C’s of carat, cut, color, and clarity. But we also can give you some jeweler’s tricks, teaching you about cut angles, diamond fluorescence, etc. that can help you find a better diamond at a lower price. By shopping with a local jeweler with a combined 100 years of experience, you are truly coming to the Diamond experts. A Federal Way Custom Jewelers diamond is sure to outshine the competition, and we are sure that she will say yes!

Did you know we have a diamond trade-up policy?

lab group one

All-natural diamonds 1/2ct and over come with a lifetime trade-up guarantee. Simply trade-in your existing diamond for one that is twice the price of the original and we will honor the full purchase price of the original diamond on the new one- making upgrades and larger diamonds more affordable. Didn’t buy your diamond from us? That’s OK too- we may still be able to offer you a trade credit toward a new purchase.
