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

Round brilliant diamonds are cut with 57–58 facets to maximize brilliance and fire. Their exceptional sparkle makes them the most popular choice for engagement rings.

Every Signora Jewels diamond is lab grown, meaning it is chemically, physically and optically identical to a mined diamond. They are certified to the same standards as mined diamonds.

Metal, Care & Fit

Choose from Sterling Silver, 9K, 14K, 18K Gold or Platinum. Clean your jewelry with warm water, mild soap and a soft brush. Store separately to preserve its shine. Most gold and platinum rings can be resized if needed.
