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 round lab grown diamond solitaire leads with a romantic signature: four prongs, each sculpted into a small polished heart, holding the center stone in place. From above the ring reads as a clean, classic solitaire — lean closer and the heart-shaped tips reveal a detail made for the occasion.

The band rises in a crossover cathedral sweep, its two polished shoulders twisting past one another as they lift the diamond. The tapered profile feels substantial on the hand while keeping every angle open to light.

Made to order and crafted with care, this ring is designed for everyday wear and the moments you'll remember forever. With no accent stones, the center diamond carries the design on its own.

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

Each of the four prongs is finished with a small sculpted heart that grips the diamond. The stone stays as secure as in a classic four-prong setting, with a romantic detail visible up close.

Are lab grown diamonds real diamonds?
Yes. They are identical to mined diamonds in chemistry, hardness, and sparkle, and are graded on the same 4C scale — the only difference is origin.
