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.

A six-prong setting holds the round center diamond securely while allowing light to enter from every direction. On each side, pear-shaped diamonds taper gracefully toward the band, creating a balanced three-stone silhouette that keeps the focus on the center while adding extra spread across the finger.

The approximately 0.80 ct round brilliant center delivers lively sparkle, while the paired pear diamonds add soft curves and visual width without overwhelming the design. Together the three diamonds create approximately 1.50 carats of brilliance in a timeless engagement ring that is comfortable enough for everyday wear.

Every ring is individually crafted by Signora Jewels. Each lab grown diamond is carefully matched, hand set and inspected before the finished ring receives its final high-polish finish.

About Lab Grown Diamonds

Round brilliant diamonds are prized for maximum sparkle, while pear-shaped side diamonds add graceful curves that complement the brilliance of the center stone. Together they create a classic three-stone design with exceptional light performance.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same international standards.

Metal, Care & Fit

Choose from Sterling Silver, 9K, 14K or 18K Gold in Yellow, White or Rose, or Platinum. Clean with warm water, mild soap and a soft brush, then dry with a lint-free cloth to maintain its brilliance.
