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 should let the center stone do the talking, and this design does exactly that. A six-prong solitaire setting lifts the diamond above a slim polished band, creating a clean, timeless profile that feels effortless on the hand.

Look closer and a hidden halo reveals itself beneath the center stone. Six accent diamonds are tucked into the gallery, adding flashes of light from the side while keeping the top view beautifully classic.

Made to order in your choice of center size and metal, this ring combines the simplicity of a solitaire with the extra brilliance and craftsmanship that make everyday wear feel special.

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

What does the hidden halo add?
The hidden halo places six accent diamonds beneath the center stone, adding sparkle from side angles while preserving a clean solitaire appearance from the top.

Which 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 based on your selected center size, metal, and ring size.
