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 elongated cushion lab grown diamond cathedral engagement ring from Signora Jewels.

A 2.00 ct elongated cushion measuring 9.15 × 6.14 mm sits in a four-prong cathedral basket above two round accents totaling approximately 0.04 ct. Approx. 2.04 ct total.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. Choose your center diamond weight and preferred metal from the options on this page.

The elongated cushion rises from a four-prong cathedral basket, while the shoulders divide into polished vines before meeting beneath the center. On this Signora Jewels ring, two 0.02 ct round diamonds sit inside the twists rather than forming a conventional pavé row.

The open spaces between the vines keep the 2.60 mm shoulders from looking heavy. At the base, the shank narrows to approximately 2.10 mm, and the 7.20 mm setting height leaves the center exposed to light from both sides.

Design highlights

Elongated cushion center shown at approximately 2.00 ct
Customizable center diamond from 1 ct to 4.5 ct
Two round side diamonds totaling approximately 0.04 ct
Four-Prong Cathedral Open Basket setting
Nature-inspired twisted vine shoulders with open spaces
Plain comfort-fit base approximately 2.10 mm wide

The two accent diamonds are placed where the polished vines cross, so they flash from the shoulders without drawing a straight line away from the center. That small detail keeps the ring organic from the front and open from the side.

About Lab Grown Diamonds

The elongated cushion combines rounded corners with a longer rectangular outline, giving the finger more visual length than a square cushion. The center and round accents are selected in F color and VS1 clarity, with Excellent cut, polish and symmetry.

Metal, Care & Fit

Choose silver, 9K, 14K or 18K yellow, white or rose gold, or platinum. Clean beneath the open basket and between the twisted shoulders with warm water, mild soap and a soft brush. Check all four center prongs during regular jewelry inspections.

FAQ

How high does the elongated cushion sit?
The cathedral setting rises approximately 7.20 mm from the finger. This height leaves the open basket visible from the side and allows light beneath the elongated cushion.

What do the two round accent diamonds add?
The two round diamonds total approximately 0.04 ct and sit within the twisted shoulders. They mark the crossing points of the vines without turning the shank into a full pavé band.

Does the twisted vine shank feel bulky?
The base is approximately 2.10 mm wide and 1.85 mm thick. Open spaces between the polished strands reduce visual weight while the comfort-fit underside remains smooth.

Can this cathedral ring be stacked with a wedding band?
A slim straight band can sit near the raised cathedral shoulders, though a small gap can remain beside the twisted sections. A contoured band follows the vine profile more closely.

Which metal emphasizes the vine pattern most clearly?
Rose and yellow gold create visible contrast between the metal and the diamonds, making the crossing vines easy to read. White gold and platinum blend with the prongs and place more emphasis on the elongated cushion.
