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.

At a glance

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

One 1.50 ct oval center, 9.40 × 6.42 × 4.02 mm, held by four prongs, with two pear side diamonds totaling 0.41 ct. Approx. 1.91 ct overall.

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

Three independently set diamonds, outward-pointing pear sides, a polished lower shank and an estimated 6.3–6.8 mm reference setting height.

Made to order in your chosen gold color and purity, with an oval center from 1 to 4.5 ct.

Signora Jewels places a 9.40 × 6.42 mm oval between two pear-cut diamonds in this three-stone engagement ring. Four rounded prongs hold the oval. Each pear has its rounded end facing the center and its pointed end turned toward the band.

The reference center weighs 1.50 ct, while the pear pair contributes 0.41 ct. The settings sit close enough to make one continuous arrangement of three diamonds, without a halo or smaller pavé stones between them.

Design highlights

1.50 ct oval-cut reference center measuring 9.40 × 6.42 × 4.02 mm
Two pear-cut lab grown diamond side stones totaling 0.41 ct
Pear side-stone reference measurement of 5.0 × 3.37 × 2.01 mm
Four rounded center prongs with separate pear side-stone settings
Plain polished lower shank measuring approximately 1.50 mm wide
Approximately 1.91 ct total diamond weight across three stones

The pear diamonds broaden the setting beside the oval before tapering toward the shoulders. Their pointed ends line up with the slim shank, so the metal takes over gradually rather than ending abruptly behind the side stones.

About Lab Grown Diamonds

The oval center and pear sides use brilliant-style faceting, but their outlines send the eye in different directions: vertically through the oval and outward along the pears. Our diamond stone guide explains how shape and facets change a diamond's appearance.

Metal, Care & Fit

Choose 10K, 14K or 18K yellow, white or rose gold. The raised three-stone head needs clearance beside a straight companion band. Brush gently around all three sets of prongs, following our jewelry care guide.

FAQ

How are the pear side diamonds positioned beside the oval?
The two pear diamonds sit horizontally, with their rounded ends facing the oval center and pointed ends extending toward the shoulders. This creates a gradual transition from the 9.40 mm reference center into the band.

Are both pear side diamonds the same size?
The supplied reference measurement is 5.0 × 3.37 × 2.01 mm for the pear side-stone design. Separate left- and right-stone measurements were not provided. The pair weighs approximately 0.41 ct combined.

Does this ring have a halo or pavé diamonds?
No. The ring contains three diamonds: one oval center and two pear-cut side stones. The remaining shank is plain polished metal without a halo or pavé detailing.

Can a straight wedding band sit flush beside this three-stone ring?
The setting height is approximately 6.3–6.8 mm, while the side-stone section measures about 3.0–3.5 mm across. These measurements do not guarantee clearance beneath the pear settings, so compare the completed ring with the intended companion band.

How should I clean around the three separate settings?
Use warm water, mild soap and a soft brush around the four oval prongs and both pear settings. Rinse thoroughly, especially where the pears meet the center, and pat dry without catching fabric beneath the prongs.
