Description
This stunning engagement ring features a round brilliant cut diamond accented with princess cut blue sapphires, all set in an ornate platinum band. It was designed for a client from Orange, CT, who shared some inspiration images with us and then described the types of modifications he wanted to make to them to achieve his ideal design.

Although he couldn’t come in personally to our Bellevue, WA showroom, we used our high-tech 3D imaging software to show him the ring we came up with. And to make sure we really had it just the way he wanted it, we created wax molds of several iterations of the design and shipped them to him for inspection and final approval before putting anything into production.
Center Diamond
The diamond at the center of this ring is nearly 2 carats, and it was supplied by the client for us to set. Its a round brilliant cut stone, and it’s displayed beautifully in this double prong setting. You can absolutely go this route and either use a gem you already have or purchase one on your own, and then bring it to us to set. But we can also source all gems for you, and if you’d like, you can come view and approve them before we put them into your piece. Diamond Engagement Rings
We can also adjust designs to accommodate smaller or larger gems to a certain extent. For instance, the inspiration ring this client wanted us to draw from included a significantly smaller main stone. Because of that, he asked that we increase the size of the accent sapphires as well to keep the proportions of the piece the same.
Sapphire Accents
Five blue sapphires run down the shoulder of the shank on each side of the center stone, and these are tapered slightly in size as they move away from the top. They’re princess cut and channel set, which keeps them almost flush with the surface of the ring and leaves no metal showing between them.
Interlocking Wedding Band
After we created the engagement ring, the client came back to us to have a custom interlocking wedding band made to go with it. The band we created wraps around the engagement ring on both sides, framing it beautifully. It includes hand engraving that matches the pattern on the engagement ring, and it also features custom filigree and milgrain beading, all of which combine to create a wonderful antique look that was just what the client was going for.
