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.

An Asscher-cut lab grown diamond three-stone engagement ring from Signora Jewels.

A 6.3 × 6.3 mm, 1.50 ct Asscher center in a raised corner-prong basket, with two tapered baguette diamonds totaling 0.44 ct. Approx. 1.94 ct across three stones.

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

Choose your center diamond weight and metal from the options on this page.

At Signora Jewels, we place a 6.3 × 6.3 mm Asscher-cut diamond between two tapered baguettes in this three-stone ring. Each side stone weighs approximately 0.22 ct. The baguettes narrow toward the polished shank, so the square center remains the widest point of the setting.

The reference Asscher weighs 1.50 ct, held at four corner positions with paired claw tips visible in the image. An open gallery leaves space beneath the step-cut facets. The lower band measures approximately 1.70 mm across and carries no pavé diamonds.

Design highlights

Asscher-cut center diamond, customizable from 1 to 4.5 ct
Two tapered baguette side diamonds, approximately 0.22 ct each
Four-corner prong basket with paired claw tips
Raised, open three-stone gallery
Plain polished shank with no pavé or halo
Approximately 1.70 mm lower band width and high-polish finish

The reference setting rises approximately 6.0–6.5 mm. Follow the lines from the Asscher's clipped corners into the two tapered baguettes: the side stones step down toward the band without an additional row of diamonds. The basket is adjusted around the chosen center weight.

About Lab Grown Diamonds

The Asscher cut uses concentric step facets inside a square outline with clipped corners. In this setting, the two tapered baguettes repeat those straight facet lines on either side of the center. The reference configuration contains three lab grown diamonds weighing approximately 1.94 ct together.

Metal, Care & Fit

Choose silver, 9K, 14K or 18K gold in yellow, white or rose, or platinum. White gold and platinum give the step-cut diamonds a cool-toned frame; yellow and rose gold create a warmer outline around the square center. Compare the metal options before making your selection.

The raised center basket and tapered side-stone settings determine how closely a wedding band can sit beside this ring. The plain lower shank measures approximately 1.70 mm wide.

For cleaning and care, use warm water, mild soap and a soft brush beneath the open gallery. Brush gently around the corner claws and the narrow ends of the baguettes. Rinse thoroughly and dry with a lint-free cloth.

FAQ

Why are tapered baguette diamonds used beside the Asscher center?
Each tapered baguette weighs approximately 0.22 ct and narrows toward the polished shank. Their straight facets continue the Asscher's step-cut pattern, creating a gradual transition from the square center to the slim band.

How is the Asscher-cut center diamond held in place?
The Asscher center sits in a raised basket with prong groups positioned at its four clipped corners. The reference image shows paired claw tips at those positions, keeping the center's straight edges visible.

Will a straight wedding band sit flush beside this three-stone ring?
The reference center setting stands approximately 6.0–6.5 mm high, with tapered baguettes extending along both shoulders. A straight wedding band needs enough clearance beside those settings; a contoured band can follow the three-stone profile more closely.

What changes when I choose a different center carat weight?
The Asscher-cut center is selectable from 1 to 4.5 ct. The 1.50 ct reference measures approximately 6.3 × 6.3 mm, and the center basket is adjusted to accommodate the selected diamond while retaining the tapered-baguette three-stone design.

How should I clean the open gallery and baguette settings?
Use a soft brush with warm water and mild soap to reach beneath the raised basket. Work gently around the corner claws and the tapered ends of both baguette diamonds, then rinse and dry the ring thoroughly.
