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.

Spotlight

The Asscher cut is loved for its striking step facets and elegant symmetry. Combined with the cathedral basket, it creates beautiful depth and dramatic flashes of light while keeping the design clean and timeless.

About Our Lab-Created Gemstones

Every center stone is a lab-created gemstone with the same essential crystal characteristics as its natural counterpart, grown rather than mined for vibrant, consistent color. Choose from all twelve birthstones—from January Garnet through December Blue Topaz—and we'll create your ring specifically for you.

Metal, Care & Fit

Available in Sterling Silver, 9K, 14K and 18K Yellow, White or Rose Gold, plus Platinum. Ruby, sapphire, garnet and topaz are excellent everyday choices. Emerald and peridot should be worn with a little extra care and should not be cleaned with ultrasonic or steam cleaners. Finished with a high polish.
