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.

This emerald lab grown diamond engagement ring balances clean architectural lines with soft brilliance from its side stones. At the center, an emerald cut diamond creates the hall-of-mirrors effect that makes this shape so distinctive and elegant.

Marquise and round accent diamonds graduate along each shoulder, drawing the eye naturally toward the center stone while adding sparkle from every angle. The result feels refined and detailed without overwhelming the emerald cut's crisp geometry.

Crafted to order in your chosen metal, this design gives you the freedom to select the center diamond size that best fits your style, budget, and story.

About Lab Grown Diamonds

An emerald cut uses long, parallel step facets that create a "hall-of-mirrors" flash rather than crushed-ice sparkle. The open table rewards a high-clarity stone and lends a clean, architectural, deco character that elongates the hand.

Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.

FAQ

Can I change the center stone size?
Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

Are lab grown diamonds real diamonds?
Yes. They are chemically, physically, and optically identical to mined diamonds and are graded using the same standards.

Will the side stones change if I select a different center size?
The ring is proportioned to suit the center diamond you choose while preserving the overall design aesthetic.

What metals can I choose?
Silver, 9K, 14K, and 18K gold in yellow, white, or rose, plus Platinum.

Is this ring made to order?
Yes. Every Signora Jewels ring is crafted to order specifically for your selected configuration.
