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 recessed diamond channel is the defining feature of this design. Instead of placing the stones on top of the ring, they sit neatly within the polished surface, giving the ring a sleek architectural look while helping protect the diamonds during everyday wear.

About Lab Grown Diamonds

The center stone is a round brilliant lab grown diamond, a shape engineered with 57–58 facets to maximize brilliance and fire. Its balanced proportions make it the most popular diamond cut for timeless men's jewelry.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond. They are graded using the same 4Cs, offer exceptional brilliance, and provide a responsible alternative with a documented origin and no mining footprint.

Metal, Care & Fit

Available in Sterling Silver, 9K, 14K and 18K Gold in Yellow, White and Rose, as well as Platinum. Platinum offers the greatest durability while gold provides classic luxury in your preferred color.

Clean with warm water, mild soap and a soft brush. Store separately to maintain the polished finish and remove before heavy manual work or harsh chemicals.

Order your regular ring size for the most comfortable fit. The tapered inner profile is designed for comfortable everyday wear despite the bold signet face.
