Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

The oval center diamond is secured within a classic four-prong cathedral basket that protects the stone while allowing generous light to enter through the open gallery beneath. Its elongated silhouette enhances finger coverage and showcases the balanced brilliance of the oval cut.

Marquise and round brilliant accent diamonds decorate each shoulder in a graceful botanical arrangement that leads naturally toward the center stone. The slim comfort shank keeps the profile refined while allowing the side accents to complement, rather than compete with, the solitaire design. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.

About Lab Grown Diamonds

The oval cut is prized for its elongated silhouette and exceptional brilliance. Marquise side diamonds echo its graceful proportions, while the round brilliant accents add subtle sparkle that enhances the overall composition without overwhelming the center stone.

Metal, Care & Fit

Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the cathedral basket and around the marquise and round accent diamonds using warm water, mild soap and a soft brush to maintain brilliance.
