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 cushion lab grown diamond bezel engagement ring from Signora Jewels.

The photographed design carries a 1.50 ct Cushion Old Mine center measuring approximately 8.2 × 6.2 mm, enclosed by a full bezel with open split-shank shoulders and no accent diamonds. Approx. 1.50 ct total.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. Choose a 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct center and your preferred metal from the options on this page.

Signora Jewels wraps the 8.2 × 6.2 mm Cushion Old Mine center in a complete rim of metal instead of using exposed prongs. At the photographed 1.50 ct weight, the bezel follows the softly rectangular outline closely, protecting the girdle while leaving the full face of the diamond open.

The shoulders divide before they reach the bezel, opening into two polished rails on either side. They spread to approximately 3.80 mm near the center before returning to a 2.20 mm lower shank. The reference setting sits approximately 6.20 mm high.

Design highlights

Cushion Old Mine center options: 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct
1.50 ct reference center measuring approximately 8.2 × 6.2 mm
Full bezel surrounding the complete perimeter of the center
No accent diamonds, keeping the Old Mine center visually isolated
Open split-shank shoulders measuring approximately 3.80 mm near the setting
Approx. 6.20 mm setting height with a 2.20 mm lower shank

The open shoulders keep a full bezel from looking heavy. From above, the polished rim draws one clean line around the cushion; immediately beside it, the shank separates and lets the skin show through.

About Lab Grown Diamonds

The Cushion Old Mine center has a softly rectangular outline rather than the strict corners of a princess or emerald cut. At the photographed 1.50 ct weight, it measures approximately 8.2 × 6.2 mm. The full bezel traces that outline closely, leaving the crown exposed while surrounding the girdle with metal.

Metal, Care & Fit

The reference construction uses approximately 5.51 g of 18K gold before the diamond is set. Yellow and rose gold create a stronger visible frame around the center, while white gold and platinum keep the bezel closer in tone to the diamond. Clean around the underside of the bezel and between the split shoulders with warm water, mild soap and a soft brush.

FAQ

How does the full bezel protect this Cushion Old Mine center?
The bezel surrounds the entire girdle with metal. That removes exposed corner prongs and gives the approximately 8.2 × 6.2 mm reference center a continuous protective edge.

What does the open split shank do beside the bezel?
The shoulders divide into two rails as they approach the center. They reach approximately 3.80 mm across near the setting, but the open middle keeps that width from becoming a solid block of metal.

How high does the 1.50 ct reference setting sit?
The photographed construction is approximately 6.20 mm high. The bezel rises above the split shoulders while remaining substantially lower than many tall prong settings.

Can a wedding band sit beside this ring?
The lower shank is approximately 2.20 mm wide, while the shoulders open and rise toward the bezel. A straight band can sit alongside the shank, though the raised center structure can create a small gap near the head.

How should I clean beneath a full bezel?
Use warm water, mild soap and a soft brush around the underside opening of the setting. The split shoulders provide additional access near the center where soap or lotion can collect.

Answers last updated August 2, 2026

When will my order ship?

Standard listed pieces are made to order with an estimated dispatch of 7 business days. Use the product-page estimate when it is more specific and the timing confirmed after ordering. Delivery timing begins after dispatch and varies by destination and carrier service. Fully custom commissions follow the production schedule confirmed with their approved specifications or CAD.

When is insured worldwide delivery free?

Orders of US$500 or more receive free express, insured and tracked worldwide delivery. Below US$500, express, insured and tracked worldwide delivery is charged at the fixed rate shown at checkout.

Will I have to pay import duties?

For every destination available at checkout, Signora prepays applicable import duties and import taxes. Customers should not be asked to pay those import charges again on delivery.

What certificate comes with my jewelry?

Every finished piece includes a Signora Jewelry Certificate. Each selected individual lab-grown center or primary diamond of 0.50 ct or above includes an IGI grading report. Below 0.50 ct, IGI can be arranged by custom request. Custom moissanite and gemstone selections include GRA documentation, with the exact scope confirmed in the approved specifications. The product page or approved specifications state the exact laboratory, report type and scope.

Can I return a made-to-order listed design?

Standard listed products are eligible for return within 30 days after carrier-recorded delivery when unworn, unused and in their original condition, with the original packaging and included documents. Normal listed choices such as metal, stone carat, chain or bracelet length, an extended ring size, or complimentary engraving do not by themselves make an item Final Sale. A sale or discount also does not imply Final Sale; only an item explicitly classified as Final Sale follows the non-returnable exclusion.

How are fully custom orders handled?

A fully custom commission is different from a listed made-to-order design. After its specifications or CAD are approved, a normal change-of-mind return does not apply. Manufacturing defects remain reviewable. Signora may accept an exceptional non-defect return case by case; documented labor and genuinely non-recoverable costs may be deducted, but these deductions are not a restocking fee.
