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.

A marquise lab grown diamond bypass engagement ring from Signora Jewels.

A 2.04 ct marquise center measuring 13.92 × 6.56 mm, held in a prong setting between two pavé curves. Twelve round accent diamonds add 0.12 ct, bringing the photographed design to 2.16 ct total.

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

Choose your center diamond weight and metal from the options on this page.

The marquise sits at the heart of this Signora Jewels design, with two diamond-set curves sweeping around it from opposite directions. Unlike a complete halo, the pavé sections leave the long edges of the center diamond exposed. The result is a distinct bypass silhouette with the marquise points defining its length.

The photographed center measures 13.92 × 6.56 mm and weighs 2.04 ct. Twelve round accent diamonds, each 1.30 mm, follow the opposing curves. The polished shank stays plain, keeping the detail concentrated around the center rather than extending down the finger.

Design highlights

Marquise center diamond, approximately 2.04 ct in the photographed design

Two opposing bypass curves frame the elongated center
12 round pavé accent diamonds totaling approximately 0.12 ct

The defining detail is the gap between the two pavé curves. They follow the marquise rather than enclosing it, leaving the center's pointed outline visible while adding diamond detail on both sides.

About Lab Grown Diamonds

The marquise cut combines pointed ends with an elongated body. Its length creates a different face-up outline from a round diamond, while the 12 round accents bring smaller points of light along the curved metalwork. Every diamond in this ring is lab grown.

Metal, Care & Fit

Choose silver, platinum, or 9K, 14K or 18K gold in yellow, white or rose. The plain polished shank contrasts with the diamond-set bypass curves.

Clean the ring with mild soap, warm water and a soft brush. Pay attention to the spaces beneath the marquise and between the pavé stones. See our jewelry care guide for ongoing care.

FAQ

How are the pointed ends of the marquise diamond secured?
The marquise is held by prongs, with shaped end prongs covering its pointed tips. The open setting leaves much of the diamond visible, so remove the ring before activities that put pressure on the center.

Is this a halo engagement ring?
No. Two separate pavé curves frame the center from opposite directions without forming a complete halo. The open spaces preserve the marquise outline and distinguish the bypass design.

Will a straight wedding band sit flush against this ring?
The curved bypass shoulders extend beyond the outline of a straight solitaire setting. A straight wedding band will leave a gap near the center, while a specially contoured band can follow the shape more closely.

How does the metal color change the appearance?
The selected metal changes the color of the polished shank and the visible bypass metalwork. Yellow and rose gold create warmer framing, while white gold, platinum and silver give the curves a cooler appearance.

How should I clean the diamonds along the curved accents?
The 12 small diamonds sit along two separate pavé sections. Use a soft brush with mild soapy water to remove buildup between the stones and beneath the raised center. Avoid abrasive cleaners and hard impacts.
