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.

Modern geometry meets timeless brilliance in this Round & Trillion Lab Grown Diamond Five Stone Engagement Ring. A brilliant round center diamond is framed by two striking trillion-cut diamonds and finished with round accent stones, creating a perfectly balanced silhouette with exceptional sparkle.

The clean, open arrangement allows each diamond to shine individually while the pointed trillion stones naturally draw the eye toward the center. Its low-profile basket setting and polished band make it comfortable enough for everyday wear while remaining distinctive for life's biggest moments.

About Lab Grown Diamonds

Round brilliant diamonds are cut with 57–58 facets for exceptional brilliance, while trillion-cut diamonds offer bold triangular flashes that add modern character and maximize the face-up appearance of the design.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same international standards. They deliver exceptional beauty, responsible sourcing and remarkable value.

Metal, Care & Fit

Available in Sterling Silver, 9K, 14K and 18K Gold in Yellow, White and Rose, together with Platinum. Most versions can be resized after purchase. Clean with warm water, mild soap and a soft brush to preserve brilliance.
