Description
This stunning engagement ring features a cushion cut diamond prong set in platinum, with round bright cut set diamond accents on the prongs, basket, and shank. It was created for a client from Los Angeles, CA, who shared his inspiration piece with us online along with some modifications he wanted to make.
Read the full description
Although he couldn’t visit our Bellevue, WA showroom personally, he communicated efficiently with our team using the online workroom we create for each custom order. In this way, he was able to see high-quality CAD renderings of the design, make the adjustments he wanted, and then approve the piece so we could put it into production.
Center Diamond
The center diamond of this ring is cushion cut and prong set in platinum. Cushion-cut diamonds are a beautiful option for the bride who is drawn to vintage-inspired engagement rings. Cushion cuts were popular for over a century and have been increasing in popularity especially with the revival of the antique style engagement rings. Diamond Engagement Rings
Diamond Accents
The basket holding the diamond, as well as the top of the knife edge shank down to the mid-point on the band, are lined with round bright cut set diamonds. These bring wonderful sparkle to the design, and they add some antique flair as well.
If you were looking to customize this design, one option might be to use a different setting style for these accent stones. For instance, you could go with a channel setting to bring a more contemporary feel to the ring. Alternately, you could add some milgrain beading to frame the accent diamonds and to add some vintage flair.
Shank Design
The shank itself features a knife edge all the way around, and this neatly divides the two rows of accent diamonds running down each shoulder. This feature works well with the angular nature of the rest of the design, which was just the look the client was after. Design Your Own Engagement Ring
