Description
This lovely engagement ring features a round brilliant cut diamond prong set in platinum, with a trapezoid diamond on either side to complete the three-stone setting. It was created for a client from Kirkland, WA, who visited our Bellevue, WA showroom personally to get his project underway.
Read the full description
As the custom design process progressed, we shared models of this piece with him through the online workroom we created for the project, and he provided feedback, which we incorporated into newer iterations of the piece. When he was satisfied that we had outlined exactly what he wanted, our client gave his approval to move the piece into production.
Three-stone Setting
The center stone in this ring is a 1.25 carat round brilliant cut diamond. It’s prong set in platinum, and a smaller trapezoid diamond sits on either side of it to complete the three-stone look. These trapezoids are oriented with their wider end up against the larger diamond, so that the way they narrow moving away from the center eases the transition to the band.

Accent Diamonds
To add a little extra sparkle to the piece, princess cut diamonds are channel set on the shank shoulders, with four on each side. Taken together, these eight stones total 0.38 carats, with is exactly the same measurement as the total carat weight of the two trapezoid diamonds from the center setting.
