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 1.00 ct oval center measuring approximately 8.2 × 5.6 mm, with two tapered baguette diamonds totaling 0.09 ct. Three diamonds weigh approximately 1.09 ct combined.

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

Individually set side diamonds with EF color and VS clarity, a polished lower shank and an estimated 5.8–6.3 mm setting height.

Signora Jewels places an 8.2 × 5.6 mm oval diamond between two tapered baguettes in this three-stone engagement ring. Rounded prongs secure the center, while separate metal supports hold the straight-edged side stones.

The reference center weighs 1.00 ct. Each tapered baguette contributes approximately 0.045 ct, giving the ring 1.09 ct across three diamonds. The baguettes sit with their wider ends facing the oval and their narrower ends leading into the shoulders.

Design highlights

1.00 ct oval-cut center measuring approximately 8.2 × 5.6 mm
Two tapered baguette side diamonds totaling 0.09 ct
Side-stone reference dimensions of 4.00 × 2.00 × 1.50 mm
Rounded center prongs and individually secured side settings
Plain polished lower shank measuring approximately 1.70 mm wide
1.09 ct total diamond weight with no halo or pavé

The baguettes add long, straight reflections beside the oval's brilliant facets. Their outer ends narrow toward the polished shank, creating a clean transition without any small diamonds along the band.

About Lab Grown Diamonds

The oval brilliant center has closely arranged facets, while the tapered baguettes show longer step-cut reflections. Our diamond stone guide explains the differences between these cuts.

Metal, Care & Fit

Choose 10K, 14K or 18K yellow, white or rose gold. The side-stone settings widen the ring near the center, so check clearance when pairing a straight band. Follow our jewelry care guide when cleaning the prongs and baguette corners.

FAQ

How are the tapered baguette diamonds positioned beside the oval?
Each baguette has a wider inner end beside the oval center and a narrower outer end facing the shoulder. Their straight step facets extend the design horizontally.

Are both baguette side diamonds identical in size?
The supplied reference measurement is 4.00 × 2.00 × 1.50 mm for the tapered baguette side-stone design. Separate measurements for the left and right stones were not provided. Together, the two diamonds weigh 0.09 ct.

Does the ring have a halo or pavé diamonds?
No. This design contains exactly three diamonds: one oval-cut center and two tapered baguette side stones. The remaining band is polished gold without smaller accent diamonds.

Will a straight wedding band sit flush beside the baguette settings?
The reference setting height is approximately 5.8–6.3 mm, while the side-stone section measures 2.5–3.0 mm wide. These measurements do not guarantee clearance, so compare the finished ring with the intended companion band.

How should I clean the narrow baguette settings?
Use warm water, mild soap and a soft brush around the center prongs and both baguette end supports. Rinse thoroughly and pat dry without pulling fabric beneath the metal contacts.
