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

The rose-cut diamond has broad triangular facets and supplies the full selected weight, since there are no halo or shoulder stones.

Metal, Care & Fit

Yellow and rose gold emphasize the border; white metals reduce that color contrast. Brush gently around the rounded corners using the care guidance.

FAQ

Does the bezel cover all four corners of the square rose-cut center?
The continuous bezel covers the square cushion’s perimeter, including all four rounded corners. Its broad rose-cut top remains exposed, so protect it from hard knocks even though there are no projecting prongs.

Is the 4.03 mm stone depth also the finished setting’s height?
The 4.03 mm measurement is the depth of the 4.00 ct reference diamond; setting height is estimated at 5.0–5.5 mm for that design. These measurements describe different parts of the ring, and both change with other center selections.

Will a straight wedding band clear the corners of this square cushion bezel?
The reference center measures approximately 10.50 mm across, while the lower shank is estimated at 1.60 mm wide. Those widths do not establish clearance beside the bezel. Compare a companion band against the completed ring, checking around the rounded corners before assuming a flush fit.

How should I clean the four inner corners of the cushion bezel?
The bezel’s inner edge follows the square cushion through four rounded corners. Use warm water, mild soap and a soft brush along that metal-to-stone junction and across the broad facets, then rinse thoroughly and pat dry. Do not push pointed tools beneath the rim.
