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 Asscher cut lab grown diamond compass engagement ring from Signora Jewels.

An approximately 3.00 ct Asscher cut diamond measuring 8.00 × 8.00 mm is secured in a compass four-prong cathedral basket with an open gallery.

Made to order in 11 metals: Silver, 10K/14K/18K Gold (Yellow, White and Rose) and Platinum.

Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.

The Asscher cut is displayed on its points in a compass setting, giving the square outline a striking diamond-shaped presentation. At Signora Jewels, four compass-positioned prongs secure the center while the cathedral basket lifts it above the shank, allowing the stepped pavilion to catch light through the open gallery.

The approximately 2.10 mm comfort-fit shank tapers gently into the cathedral shoulders, creating a balanced profile beneath the bold 3.00 ct center. The approximately 7.80 mm setting height gives the Asscher cut the elevation it needs while maintaining a clean and refined silhouette for everyday wear.

The compass orientation transforms the traditional square Asscher into a bold geometric focal point. Broad step facets create mirror-like reflections while the cathedral basket keeps the profile open and allows light to reach the pavilion from below.

About Lab Grown Diamonds

The Asscher cut is celebrated for its concentric step facets and deep hall-of-mirrors effect. Every center diamond is F color, VS1 clarity and , selected to complement the proportions of this compass cathedral design.

Metal, Care & Fit

Available in Silver, 10K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the open basket using warm water, mild soap and a soft brush to maintain the brilliance of the stepped facets. Inspect the compass prongs periodically to ensure the center remains securely held.

FAQ

Why is the Asscher cut set in a compass orientation?
The compass setting rotates the square diamond onto its points, creating a distinctive geometric appearance while emphasizing the symmetry of the Asscher cut.

What does the cathedral basket add to the design?
The cathedral shoulders support the basket from below while raising the center into stronger light. This creates an open side profile and improves access for cleaning.

Can this ring be worn with a wedding band?
Yes. The raised cathedral basket allows many straight wedding bands to sit close, while contoured bands can follow the profile more precisely.

Which metal color best suits an Asscher cut?
White gold and platinum emphasize the crisp step-cut geometry, while yellow and rose gold create warm contrast around the square center diamond.
