Description
This beautiful engagement ring features a radiant cut diamond set in the center of a halo of custom cut blue sapphires, and accented with custom hand engraving and milgrain on the platinum band. It was created for a couple from Miami, FL, and they were so happy with the way it turned out that they came back to us when it was time to have a wedding band made. Design Your Own Engagement Ring

Center Diamond and Halo
The main diamond in this ring is 1.31 carats and radiant cut. It’s double prong set in platinum at the center of a squared halo of blue sapphires, and the contrast with the rich blue of these accent stones only helps intensify its gorgeous sparkle. The sapphires themselves were specially cut so that they fit seamlessly together in the halo, creating an unbroken ring of blue around the diamond.
Diamond and Milgrain Accents
At the top of the cathedral shank shoulders, a leaf shape creates the bridge from band to main setting. A single round diamond is bright cut set in the center of this detail on each side, and this adds a lovely sparkle along with a bit of vintage flair.
The vintage theme is also enhanced by the addition of milgrain accents surrounding the halo, lining the basket, and on the edges of the band. The vintage look was really what the clients were after, and we made sure every detail was consistent with this style. Vintage Engagement Rings
Custom Filigree and Hand Engraving
An elegant hand-engraved wheat pattern covers the top and fronts of the band, and we used the same pattern on the matching wedding band that we later made for this same couple. To ensure a perfect match for the engraving, we had to borrow the engagement ring during the production of the wedding band, and this also enabled us to contour the wedding band so the two would fit seamlessly together. Matching Wedding Sets
The basket below the main setting is another custom touch, as it’s formed from hand-made filigree lined with milgrain. Both the filigree and engraving can be customized to include a pattern or symbol with personal significance to you and your partner, and this gives you a wonderful way to add special meaning to your wedding set.
