Signora Jewels puts the oval at the center of a ring with more going on underneath than you see at first glance. The photographed center is 8.92 × 6.88 mm face-up, held by six prongs, while larger round diamonds sit in circular stations immediately beside it. Smaller rounds continue through the structured shoulders.
The CAD measures the top of the ring at 21.20 mm across and 10.85 mm through the center area. From the side, the gallery opens beneath the oval instead of closing it behind a wall of metal. The lower band measures 1.75 mm, with a 2 mm profile shown in the CAD.
Design highlights
- 1.800 ct reference oval measuring 8.92 × 6.88 × 4.76 mm
- Six-prong center setting with an open gallery beneath the diamond
- 6 round diamonds at 1.75 mm totaling 0.120 ct
- 12 round diamonds at 1.20 mm totaling 0.072 ct
- 19 diamonds and 1.992 ct total in the CAD reference design
- Sculpted polished shoulders broken up by circular diamond stations
The larger 1.75 mm rounds act as transition stones between the oval and the band, while the 1.20 mm diamonds add smaller points of light farther through the shoulders. That change in scale keeps the center visually dominant. Explore more engagement rings, compare shapes in the diamond stone guide, or review the available choices in the metal guide.

About Lab Grown Diamonds
The CAD reference oval weighs 1.800 ct and measures 8.92 × 6.88 × 4.76 mm. Two round accent sizes surround it: six 1.75 mm stones totaling 0.120 ct and twelve 1.20 mm stones totaling 0.072 ct. Together, the reference ring carries 19 diamonds at 1.992 ct total.
Metal, Care & Fit
The CAD gives an 18K finished metal weight of 3.35 g before stones. The open gallery provides access beneath the oval, while the circular accent stations and smaller shoulder settings need brushing from both sides. Use warm water, mild soap and a soft brush, then rinse thoroughly around the smaller 1.20 mm stones.
FAQ
How many accent diamonds are in this oval ring?
There are 18 accent diamonds totaling 0.192 ct in the CAD reference design. Six measure 1.75 mm and twelve measure 1.20 mm.
How is the oval center held?
The product image shows six prongs around the oval center. The gallery beneath the stone is open, leaving access behind the 8.92 × 6.88 × 4.76 mm reference diamond.
What do the two accent sizes do?
The six 1.75 mm rounds create the larger diamond stations, while twelve 1.20 mm rounds supply the smaller shoulder accents. The size change steps the eye down from the 1.800 ct oval into the band.
How wide is the ring across the top?
The CAD measures the top at 21.20 mm across and 10.85 mm through the center area. The lower band is marked at 1.75 mm.
How should the open gallery and accent settings be cleaned?
Use a soft brush with warm water and mild soap from the underside as well as the top. Pay particular attention behind the oval and around the 18 smaller diamonds, where residue can settle.
