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 vintage engagement ring pairs clean architectural lines with delicate heirloom-inspired detailing. The elongated emerald cut center stone creates a sophisticated presence, while marquise-shaped side accents and fine milgrain borders add texture, sparkle, and character from every angle.

Four claw prongs secure the emerald cut diamond while allowing the distinctive step facets to take center stage. The flowing side-stone arrangement softens the geometry of the center stone and creates a graceful transition into the polished band.

Made to order in your chosen center size and precious metal, this design offers the timeless elegance of an emerald cut engagement ring with the flexibility to make it uniquely yours.

About Lab Grown Diamonds

An emerald cut uses long, parallel step facets that create a hall-of-mirrors effect rather than crushed-ice sparkle. The open table rewards a high-clarity diamond and gives the ring a clean, architectural elegance that has remained popular for generations.

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.

FAQ

Yes. All 14 accent diamonds shown in the design are included with every version of this ring.

Does the milgrain detailing affect durability?
No. The milgrain detailing is integrated into the design and crafted for everyday wear while adding vintage character to the ring.

Does the price include the center diamond?
Yes. The listed configuration includes the center lab grown diamond; you can adjust size and metal selections and the price updates automatically.

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

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.
