Description
This dazzling engagement ring features a round brilliant cut diamond double prong set in platinum, with three marquise shaped diamond accents on each side. It was created for a couple from Bellevue, WA, and they were so happy with the way it turned out that they came back to us for a matching wedding band.

Center Diamond
The centerpiece of this ring is a 2.01 carat round brilliant cut diamond. The platinum double prongs holding it in place rise straight up from the base of the cathedral shank, and the space between them on the ring fronts are filled with an inverted heart shape.
Platinum is an excellent choice for a ring like this, particularly due to the large size of the diamond. It’s an exceptionally strong yet lightweight metal, and it will hold up well to the rigors of everyday wear. Platinum also maintains its slivery shine without the need for periodic replating, as is necessary with white gold.
Marquise Diamond Accents
There are three marquise shaped diamonds on either side of the center stone, and these are all bezel set. They’re arranged with two closer to the top, seeming to cradle the sides of the main setting, while the third is in line with the rest of the band. The shape and placement of these accents gives them a vaguely floral quality, a touch which adds some organic overtones to the design. Custom Engagement Rings
Matching Wedding Sets
The wedding band we made to match this engagement ring utilizes the same size marquise shaped diamonds in bezel settings, creating a definitive link to the engagement ring. This type of shared feature can help make your wedding set truly spectacular, especially since you’ll likely always wear both of them together. Diamond Engagement Rings
These clients opted to have their engagement ring and wedding band fused together, which is a good option if you know you’ll never wear them individually. Especially for rings with larger stones like this one, it can help keep it from spinning on your finger, and it will also ensure that both rings are always perfectly aligned.
