Whether you know exactly what sorts of adjustments you’d like to make or are looking for some guidance along the way, our experts are always available to discuss your ideas, either in person in our Bellevue, WA showroom or through our website. Once we know what you’re interested in, we’ll put together a set of CAD proofs for you to review, and only when you’re completely satisfied with our models will we turn your project over to our expert artisans to begin production.
Three-stone Setting
The centerpiece of this ring is a one carat round brilliant cut diamond. It’s held in place by four platinum prongs that rise nearly straight up from the inner margin of the band below. On either side of this gorgeous stone, a smaller round diamond sits in a three prong setting that nestles it up against the side of the center. Diamond Engagement Rings
Two of the prongs in each side setting tuck just inside the prongs holding the main diamond, while the third sits inline with the band. This arrangement enhances the tapering look of the center setting as a whole, easing the transition to the narrower shank below.
Customization Options
If you’re interested in customizing this ring, you might want to start by choosing a different type of stone for the side positions. Blue and pink sapphires are popular choices in situations like these, and there are many other options to explore as well. Alternately, you could use a sapphire in the center spot while keeping the white diamonds on either side, and you may also want to change the shape of the stones to create precisely the look you’re after.
