Description
This stunning engagement ring features a radiant cut blue sapphire prong set in white gold, with bezel and bright cut set diamond accents on the milgrain-lined cathedral shank. It was created for a couple from Kirkland, WA, who initially visited our Bellevue, WA showroom to get an idea of the type of ring they wanted.

After our team discussed options with them onsite, we came up with a unique design that we then shared via the online workroom we created for the project. In fact, we gave them two variations in the initial design phase of the project, and they chose the one they liked best. They also requested a couple of slight adjustments to the CAD models we created, and they did come in to view a wax mold of the piece to make sure everything was just the way they wanted it before we cast the ring in metal.
Center Sapphire
The lovely blue sapphire at the center of this ring is radiant cut and 2.71 carats. It sits in a four prong setting made of 18k white gold, and its angular shape works nicely with the other elements of the ring design. Our clients wanted to make sure they got the perfect sapphire for this piece, and so we brought in several beautiful stones for them to choose from, with this being the one that captured their hearts.
Diamond and MIlgrain Accents
Just next to and slightly below the main sapphire, bullet shaped diamonds are bezel set, one on each side, with their wider ends up against the main setting. These are lined with bright cut set diamonds, which come to a point before joining the main part of the band. And helping to unify these two sections of the ring further, four round bright cut set diamonds run down the side of the main shank as well, ending right at the mid-point on the band.
All of these accent diamonds are lined with milgrain beading, which helps to cement the vintage style of the ring. For a bit of peek-a-boo sparkle, a princess cut diamond lined with milgrain is bezel set on each of the ring fronts just below the center setting.
Custom Wedding Sets
After we made this ring, the clients were so happy that they came back to us for both his and her’s wedding bands. We made contoured wedding ring #102784 to sit flush up against this piece, and to ensure the two rings were a perfect match, we borrowed the engagement ring during the production of the wedding band so that we could line them up perfectly.
