Center Setting
At the center of this ring, a 0.75 carat round brilliant cut diamond is cradled in a four prong platinum setting that emerges from an ornate section directly below the diamond. This type of setting is a classical choice, and it leaves the diamond open on all sides so that plenty of light can reach it, helping to highlight its brilliance.
Diamond and Milgrain Accents
Split prong set diamond accents run down both shank shoulders, continuing to the three-quarter point on each side of the band. These bring a glamorous sparkle to the piece, as well as some classical flair. The split prong setting leaves very little metal visible around the stones, and the diamonds are exactly as wide as the top surface of the narrow band. Diamond Engagement Rings
Below the main setting, a floral design is bright cut set with small diamond accents and lined with milgrain, creating an intricately detailed section with organic overtones. This adds a hint of vintage flair to the design as well, and it’s a detail you can work with our team to customize to reflect a symbol of personal significance to you. Unique Engagement Rings
Custom Wedding Sets
If you’d like to customize this ring as part of a complete wedding set, our experts will help you determine what type of wedding band would best complement it to achieve the look you’re after. Even if you don’t want to have both rings made at the same time, it’s a good idea to think about the type of wedding ring you’d eventually prefer so that you can be sure it will be compatible with the design of your engagement ring.
