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.

FAQ

Are the long edges of this four-prong rose-cut oval enclosed by metal?
Four claws touch the oval at its rounded ends and side midpoints, leaving sections of its curved edges exposed. The setting does not surround the diamond with a continuous metal border. Keep those edges clear of hard knocks and remove the ring for lifting or workouts.

Will every oval rose-cut center measure 13.5 × 8.5 mm?
The approximately 13.5 × 8.5 mm dimensions describe the 3.00 ct reference center only. The 1–4.5 ct options retain the oval rose cut and Four-Prong arrangement, while the diamond’s dimensions and setting proportions vary with the selection.

What should I check before stacking beside the oval’s side claws?
The side claws sit where the shoulders meet the oval, so the lower shank’s estimated 1.70 mm width does not establish clearance around the center. Compare a companion band against the finished ring to check that it does not press against either side claw or the diamond.

How should I clean the rose-cut face around its four claws?
The rose-cut center leaves broad facets visible between four separate claw tips. Use warm water, mild soap and a soft brush across the face and around each metal-to-stone contact, then rinse thoroughly and pat dry without pulling cloth beneath the tips.
