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.

An oval-cut lab grown diamond three-stone engagement ring from Signora Jewels.

One 1.50 ct oval center, approximately 9.2 × 6.4 mm, with two pear side diamonds totaling 0.27 ct and 4–6 round accents totaling 0.07 ct.

Made to order in 10K, 14K and 18K gold, available in yellow, white and rose gold.

Approximately 1.84 ct total diamond weight across 7–9 diamonds, with a polished lower shank and raised center setting.

Signora Jewels sets a 9.2 × 6.4 mm oval between two pear-cut diamonds in this three-stone engagement ring. Four prominent rounded claws hold the center. The pears point outward, narrowing toward the shoulders.

Beyond each pear, small round diamonds sit apart from one another, with polished gold visible between their settings. There are approximately 4–6 rounds weighing 0.07 ct in total. The pears contribute another 0.27 ct, giving the reference ring 1.84 ct across all its diamonds.

Design highlights

1.50 ct oval-cut reference center measuring approximately 9.2 × 6.4 mm
Two outward-pointing pear-cut side diamonds totaling 0.27 ct
Approximately 4–6 spaced round shoulder diamonds totaling 0.07 ct
Raised center setting with prominent polished claw prongs
Vintage-inspired metalwork around the pear side settings
Plain polished lower shank measuring approximately 1.80 mm wide

The pear diamonds sit beside the oval's widest section. Past their pointed ends, the round accents continue toward the plain lower band. The polished gaps keep the shoulder pattern open rather than forming a continuous pavé strip.

About Lab Grown Diamonds

The oval and pear cuts create reflections along the center and side stones, while the smaller round diamonds introduce separate flashes down the shoulders. Read our diamond stone guide to compare these cuts.

Metal, Care & Fit

Choose 10K, 14K or 18K yellow, white or rose gold. The raised three-stone head needs clearance beside a companion band. Clean around the pear settings and spaced round diamonds, following our jewelry care guide.

FAQ

How do the pear side diamonds sit beside the oval center?
Two pear-cut diamonds sit horizontally, with their rounded ends beside the oval and their points facing toward the shoulders. Together, the pears weigh approximately 0.27 ct.

Are the small shoulder diamonds set in continuous pavé?
No. Approximately 4–6 round brilliant diamonds sit separately along the shoulders, with polished gold between them. They contribute approximately 0.07 ct without forming an uninterrupted pavé strip.

How is the 1.84 ct diamond weight divided?
The reference oval center weighs 1.50 ct, the two pears total 0.27 ct, and the round shoulder diamonds add 0.07 ct. Together, they total approximately 1.84 ct.

Can a straight wedding band sit flush beside this ring?
The reference setting rises approximately 6.5–7.0 mm, while the pear side-stone section spans approximately 3.2–3.8 mm. Check the completed ring against the intended companion band to establish clearance beneath the side settings.

How should I clean the pear settings and round accents?
Use warm water, mild soap and a soft brush around the center prongs, both pear settings and the individually spaced round diamonds. Rinse thoroughly and pat dry without pulling fabric through the small metal contacts.
