Diamond Engagement Rings
At Federal Way Custom Jewelers, we do diamonds differently. So Should you.


We are proud to do diamonds differently. We offer top-quality diamond rings and loose diamonds presented in a low-pressure environment. Most of our diamonds are kept unmounted, such that our diamonds 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 have some 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.
