Description
This dazzling engagement ring features a round brilliant cut diamond in a six prong setting atop a split platinum shank, accented with bright cut set diamonds and milgrain beading. It was created as a custom piece for a client, who came into our Bellevue, WA showroom personally to get the custom design process under way.

After viewing several sample designs, she settled on the ring she wanted to customize, and our team incorporated her desired changes into the CAD models we then shared with her online. She requested a few more adjustments after seeing these models, and once we’d implemented those, she came in again to view a wax model before giving her final approval to move her piece into production.

Center Setting
At the top of this ring, a 1.01 carat round brilliant cut diamond is displayed beautifully in a six prong platinum setting. Each of the prongs holding the diamond are formed from the union of two ends of the U shapes that repeat all the way around the basket below the center stone. The bottom of the U’s rest on a band of metal that lies on its side at the top of the ring, connecting the two sides of the band, and this forms a pedestal at the base of the center setting. Unique Engagement Rings
Diamond and Milgrain Accents
Round bright cut set diamonds run up both shank shoulders in two rows continuing all the way up, with one row on each strand after the band splits close to the top. The fronts of the band are lined with bright cut set diamonds as well, and these taper moving away from the top in order to fit in the space available.
Bright cut set diamonds also run all the way around the ring at the base of the center setting, as well as along a second ring lower down. These bring a glamorous sparkle to the piece, and their placement helps unite the separate sections of the ring. To further this unifying effect, milgrain beading lines all diamond accents, as well as the U shapes on the sides of the main setting.
