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 round lab grown diamond chevron anniversary ring from Signora Jewels.

The CAD uses 5 round diamonds at 3.50 mm and 4 marquise diamonds at 6.15 × 3.10 mm. The center round is 0.167 ct, the remaining 8 side diamonds total 1.568 ct, and all 9 diamonds total 1.735 ct.

The diamond-set top measures approximately 20.20 mm across and 8 mm high, with a 3.20 mm upper profile.

The photographed ring has an open V-shaped arrangement of alternating round and marquise stones over a plain polished lower shank.

Signora Jewels uses the change in diamond shape to build the curve of this ring. A 3.50 mm round sits at the center point, with marquise cuts angled outward on both sides and additional rounds carrying the line toward the shoulders. Each stone is individually prong set, leaving visible breaks between the diamonds rather than joining them into a solid pavé surface.

The CAD gives four marquise diamonds at 6.15 × 3.10 mm and five rounds at 3.50 mm. Together they cover approximately 20.20 mm across the top. The lower band remains plain, measuring 1.60 mm in the CAD.

The marquise cuts do most of the directional work. Their pointed ends follow the rising V, while the rounds break up that line with compact flashes between them. Browse more anniversary rings, compare diamond shapes in the diamond stone guide, or review choices in the metal guide.
