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.

At a glance

A full-eternity round Lab Grown Diamond ring from Signora Jewels.

Twenty-five round diamonds measure approx. 2.50 mm each and total approx. 1.625 ct.

Shared prongs hold a continuous diamond line around the entire approx. 3.31 mm-wide band.

Made to order in silver, 9K/14K/18K yellow, white or rose gold, and platinum.

Made to order — select your metal above.

Signora Jewels spaces all 25 diamonds around the full circumference, so the line of light does not stop at the palm. Shared prongs sit between neighboring stones, using less visible metal than separate four-prong baskets. Explore coordinating wedding bands.

The open gallery leaves the lower half of every 2.50 mm diamond accessible to a soft brush. From the side, the repeated arches keep the band airy; from above, the stones form one continuous 3.31 mm-wide row.

This is a full-eternity construction, so the diamond settings continue beneath the finger. Accurate sizing matters because the stone line leaves less plain metal for later adjustment. Check the ring size and fit guide before ordering.

About Lab Grown Diamonds

Round brilliant diamonds return light through a compact facet pattern. Repeating the same 2.50 mm size around the entire ring creates an even rhythm with no larger focal stone.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K contains more strengthening alloy, while 18K contains more gold and carries richer color; compare every option in the metal guide.

Clean between the shared prongs and beneath the open gallery with warm water, mild soap and a soft brush. Store the ring separately so the exposed diamond girdles do not rub against other jewelry.

FAQ

How many diamonds are in the ring?
The ring contains 25 round Lab Grown Diamond stones. Each measures approximately 2.50 mm.

What is the total diamond weight?
The total diamond weight is approximately 1.625 ct. The full weight comes from the continuous line of 25 diamonds.

Does the diamond line continue underneath the finger?
Yes. This is a full-eternity band, so the diamonds and shared-prong settings continue around the complete circumference.

Can this eternity ring be resized?
Full-eternity rings have limited resizing room because diamonds occupy the entire band. Ordering the correct size before production protects the spacing and security of every setting.

What is the difference between shared-prong and channel setting?
Shared-prong setting uses small prongs between neighboring diamonds, while channel setting holds stones between two continuous metal walls. Shared prongs expose more of each round diamond from above and from the side.

Can I wear this ring every day?
Yes. The 2.50 mm diamonds sit in low repeated settings, though the full diamond circumference should be protected from heavy lifting and hard impacts.

What is the difference between 9K and 18K gold?
9K gold contains more strengthening alloy and has a harder surface, while 18K contains more gold and carries richer color. Both are solid gold choices for this eternity band.

What is included with the finished ring?
Signora Jewels includes all 25 diamonds and the selected made-to-order metal in the completed full-eternity ring.
