Sapphire Center
The centerpiece of this ring is a 3.50 carat cushion cut blue sapphire, and it’s cradled in four platinum prongs that emerge from the rounded corners of the surrounding diamond halo. Although diamonds are generally considered the most traditional choice for the center stone in an engagement ring, sapphires have been used extensively in this role as well, and this particular stone exhibits a rich blue color that contrasts nicely with the silvery shine of the platinum it’s set in.

Diamond Halo and Accents
A contoured halo of bright cut set diamonds surrounds the center sapphire, and bright cut set diamonds line the sides of the halo all the way around. They also continue down both shank shoulders, tapering in size along with the band until they stop at the mid-point on the sides. Additional diamond accents run along this same segment of the band on both ring fronts, and they continue across the bridge piece that connects one side of the band to the other by passing directly below the main setting.

Milgrain and Filigree
Milgrain beading lines all rows of accent diamonds, including those in the halo, and it lines the custom filigree below the center sapphire on the ring fronts. This intensifies the vintage look of the piece, and it brings a nice, finished feel to the design. The filigree in this piece is in a repeating V pattern, but it can be customized in a variety of ways to incorporate a symbol or shape with special significance to you and your partner.
