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.

About Lab Grown Diamonds

Choose the oval lab grown diamond from 1 to 4.5 ct; with no accents, the selected center sets the total carat weight.

Metal, Care & Fit

Yellow and rose gold emphasize the four claws; white metals reduce the contrast. Clean around each tip using the care guidance.

FAQ

How exposed are the rounded ends of this four-prong oval?
The four claws sit along the oval’s sides rather than directly over its rounded ends. Those ends remain visible, so avoid hard knocks to the exposed edges and remove the ring for lifting or workouts.

Do the 9.0 × 6.5 mm measurements apply to every oval center option?
The approximately 9.0 × 6.5 mm measurements describe the 2.00 ct reference center only. Other carat choices have their own stone dimensions; the Four-Prong setting style and plain-band design remain.

Does the 1–4.5 ct selection include diamonds on the oval ring’s shoulders?
The 1–4.5 ct selection is for the single oval center; the shoulders contain no diamonds. With no halo or accent stones, the selected center weight is also the ring’s total diamond weight.

How should I clean around this oval’s four individual claw tips?
The four claw tips meet the oval at separate points along its edge. Use warm water, mild soap and a soft brush around each contact point, then rinse and pat dry without pulling cloth through the gaps beneath the tips.
