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

A round brilliant lab grown diamond bypass engagement ring from Signora Jewels.

The 1.00 ct center measures approximately 6.4–6.5 mm and sits between pavé-set sweeping shoulders with 12 round brilliant accents totaling 0.15 ct. Approx. 1.15 ct overall.

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

Made to order with a fixed 1.00 ct center. Choose your preferred metal and color.

At Signora Jewels, we set the 6.4–6.5 mm round brilliant between two shoulders that sweep past each other instead of meeting in a straight line. The bypass engagement ring holds the center with four rounded prongs, turned so one sits above and another below the diamond.

Twelve round brilliant accents total approximately 0.15 ct along the curved shoulders. The diamond-set sections measure approximately 3.2–3.8 mm across the bypass before narrowing to a 1.70 mm lower band.

Design highlights

Fixed 1.00 ct round brilliant center, approximately 6.4–6.5 mm
Four-prong center setting with raised basket
12 round brilliant accent diamonds totaling approximately 0.15 ct
Asymmetrical bypass shoulders sweeping around the center
Pavé-set curved strands with no surrounding halo
High-polish lower band, approximately 1.70 mm wide at the base

The sweeping shoulders frame the round center from opposite directions. Each carries its diamond line toward the stone, leaving the polished gold curves visible beside the four prongs.

About Lab Grown Diamonds

The center and all 12 shoulder accents are round brilliant lab grown diamonds. The 1.00 ct center sits within the twisted shoulder arrangement rather than inside a halo, with approximately 0.15 ct of smaller diamonds following the curves.

Metal, Care & Fit

Choose silver, yellow gold, white gold, rose gold or platinum. Compare the metal options before choosing your finish. The lower band measures approximately 1.70 mm wide and 1.60 mm thick, with a reference setting height of approximately 6.0–6.5 mm.

For cleaning and care, use warm water, mild soap and a soft brush along the curved pavé strands and beneath the raised center. Rinse thoroughly and dry with a lint-free cloth.

FAQ

How does the bypass setting hold the round center?
The 1.00 ct round brilliant sits in a raised four-prong basket between two shoulders sweeping in opposite directions. The center remains visually separate from the curved pavé strands rather than being enclosed by a halo.

How many diamonds are along the bypass shoulders?
There are 12 round brilliant shoulder diamonds totaling approximately 0.15 ct. Combined with the 1.00 ct center, this ring contains 13 diamonds with an approximate total weight of 1.15 ct.

Will a straight wedding band sit flush beside the twisted shoulders?
The bypass sections measure approximately 3.2–3.8 mm across and curve around the raised center. A straight wedding band needs clearance beside those sweeping shoulders; a contoured band can follow their asymmetrical profile more closely.

How should I clean the pavé diamonds on the curved shoulders?
Use mild soap, warm water and a soft brush around the 12 small diamonds and the spaces beside the curved metal strands. Brush gently around their prongs, rinse thoroughly and dry with a lint-free cloth.
