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 round lab grown diamond engagement ring is loved for one reason above all others: brilliance. This classic solitaire places a round center diamond in an elegant six-prong setting that allows light to enter from every angle, maximizing sparkle across the stone.

The slim high-polish band keeps the focus where it belongs — on the center diamond. Delicate accent diamonds tucked into the gallery add a subtle detail visible from the side, creating extra light without changing the clean solitaire appearance from above.

Made to order in your preferred metal and center size, this ring is designed for those who want a timeless engagement ring with refined craftsmanship and everyday comfort.

About Lab Grown Diamonds

A round brilliant is cut with 57–58 facets engineered to recycle light back to the eye, which is why it out-sparkles every other shape and hides small inclusions well. It is the most requested engagement silhouette and sits comfortably in solitaire, halo, or pavé settings without fighting the design.

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.

What are the hidden accent diamonds?
Two small round diamonds are set within the gallery beneath the center stone, adding subtle sparkle from the side profile.

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

Will this ring keep its sparkle?
Yes. Lab grown diamonds have the same hardness and durability as mined diamonds, rating 10 on the Mohs scale and designed to last a lifetime.
