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.

Each baguette contributes approximately 0.075 ct and narrows toward the plain band, which measures approximately 1.50 mm across at its base. No pavé follows the side stones.

About Lab Grown Diamonds

The cushion’s curved outline contrasts with the straight facet lines of the step-cut baguettes.

Metal, Care & Fit

Yellow gold outlines the four claws; white metals soften that contrast. Clean around the baguette end caps with a soft brush, and check wedding-band clearance beside the side settings.

FAQ

Why are tapered baguettes paired with this cushion center?
The two baguettes total approximately 0.15 ct and narrow from the cushion toward the plain band. Their straight step facets contrast with the cushion’s rounded corners without adding a halo around it.

What changes when I choose a cushion center other than 1.50 ct?
The center is selectable from 1 to 4.5 ct, and the approximately 7.3 × 6.5 mm dimensions belong to the 1.50 ct reference. The center setting is made around the selected diamond, so the reference dimensions and 1.65 ct total do not apply to every option.

Will a straight wedding band fit beside the cushion and tapered baguettes?
The baguette settings occupy both shoulders, and the estimated 6.0–6.5 mm setting height does not establish the clearance beneath them. A flush fit depends on the wedding band’s profile and that clearance; confirm both against the finished setting before pairing the rings.

How should I clean where the cushion meets the two baguettes?
Small prongs secure the inner ends of both baguettes beside the cushion’s four corner claws. Use warm water, mild soap and a soft brush around these junctions and the outer end caps, without levering the prong tips. Rinse thoroughly and dry with a lint-free cloth.
