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

An emerald Lab Grown Diamond cathedral engagement ring from Signora Jewels.

As shown: one approx. 2.00 ct emerald-cut center measuring 11.00 × 9.00 mm, secured by four corner prongs with no accent diamonds.

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

Choose a center from 1 to 4.5 ct; the basket and metal weight scale with the selected diamond.

Made to order — the price updates with your selection. Change the center proportions or shoulder height through our custom jewelry service.

Signora Jewels sets the 11.00 × 9.00 mm emerald cut above two rising cathedral shoulders, leaving the broad step facets unobstructed from the front. Four corner prongs hold the stone without interrupting its straight sides.

The polished shoulders climb into the basket, then taper into a plain lower shank. That lift keeps the center visible from the side and gives a wedding band room to sit close beneath it.

There are no accent diamonds competing with the hall-of-mirrors pattern. You see long flashes across the table, then a clean strip of metal running around the finger.

About Lab Grown Diamonds

An emerald cut uses long step facets to create broad flashes instead of the smaller scintillation seen in a brilliant cut. The open four-prong basket keeps those straight edges and clipped corners visible.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded on 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 has more strengthening alloy for daily wear, while 18K has higher gold content and richer color; compare them in the metal guide.

Order in your known US size. The raised cathedral shoulders give the ring more structure near the center, so accurate sizing helps keep the emerald cut upright; use the ring size and fit guide. Clean beneath the basket with warm water, mild soap and a soft brush.

FAQ

Can I choose another center diamond size?
Yes. The emerald-cut center is available from 1 to 4.5 ct, and the basket and metal weight scale to the selected carat. The photographed configuration uses an approx. 2.00 ct center measuring 11.00 × 9.00 mm.

Are there any side or pavé diamonds?
No. This is a single-diamond solitaire with no halo, pavé or side stones. The full diamond weight comes from the emerald-cut center selected.

How is the emerald-cut diamond held?
The center is secured by four prongs positioned at the clipped corners. This protects the corners while leaving the long step-cut sides open and easy to see.

What does a cathedral setting do?
A cathedral setting raises the shoulders of the band until they meet the center basket. The shoulders support the head from both sides and create an open arch beneath the diamond.

Will a wedding band sit beside this ring?
A straight wedding band sits close beneath the raised basket. The exact gap depends on the wedding band’s height, while a contoured band follows the cathedral profile most closely.

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 daily engagement-ring wear.

How do lab grown diamonds compare with mined diamonds?
Lab grown diamonds match mined diamonds in carbon structure, hardness and optical behavior; their origin is different. Signora Jewels supplies this ring only with Lab Grown Diamond stones.
