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 princess cut lab grown diamond engagement ring from Signora Jewels.

A 5.55 × 5.55 mm princess cut center diamond weighing approximately 1.01 ct is secured in a compass four-prong setting above an open basket gallery. Thirty round brilliant accent diamonds add approximately 0.21 ct across the infinity shank.

Made to order in 11 metals: Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum.

The square center diamond is rotated into a compass orientation so each corner points toward the band rather than sitting flat. Four rounded prongs secure the corners while the open basket beneath the stone allows light to reach the pavilion and keeps the profile open when viewed from the side.

The infinity shank twists beneath the center before separating into polished and micro pavé sections. Thirty round brilliant diamonds follow one side of the twist, creating a flowing line of sparkle that wraps naturally toward the center stone. Signora Jewels makes every ring to order in your selected precious metal.

About Lab Grown Diamonds

The princess cut combines sharp corners with bright reflections across the table, creating a crisp, geometric appearance. The compass orientation gives the diamond a distinctive look while preserving the classic proportions of the cut.

Metal, Care & Fit

Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean the open basket and micro pavé diamonds with warm water, mild soap and a soft brush to remove everyday residue from between the accent stones.

FAQ

Why is the princess diamond set in a compass position?
The compass orientation turns the square diamond diagonally, creating a distinctive appearance while keeping all four corners protected by the prongs.

Does the twisted infinity shank affect comfort?
No. The twist is concentrated around the top of the ring, while the lower portion of the band remains smooth against the finger.

Will the micro pavé diamonds sparkle from the side?
Yes. The accent diamonds continue along the twisted shoulder so light reaches the pavé from multiple angles as the ring moves.

Can this ring be worn every day?
Yes. The open basket, four-prong setting and solid cathedral-style support are designed for everyday wear while keeping the center diamond securely positioned.

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.
