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 is designed for someone who loves bold proportions and clean architectural lines. At its center sits a striking emerald cut diamond, framed by tapered baguette side stones that draw the eye toward the hall-of-mirrors flash unique to this shape.

The elevated basket reveals a hidden row of diamonds beneath the center while pavé-set diamonds continue along the shoulders, adding sparkle from every angle without distracting from the strong geometry of the emerald cut.

Made to order in your choice of center size and metal, this three-stone design balances presence, comfort, and everyday wearability while creating a memorable engagement ring built around your preferences.

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. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same 4C scale.

Will an emerald cut sparkle like a round diamond?
An emerald cut produces broad flashes of light through its step facets rather than the intense scintillation of a round brilliant, giving it a refined and architectural appearance.

What side stones are included?
The design includes two tapered baguette diamonds and additional round accent diamonds along the gallery and shoulders, exactly as shown.

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