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.

A blue cushion lab grown diamond side stone engagement ring from Signora Jewels.

A 2.00 ct, 8.20 × 6.50 mm blue cushion center sits in a Four-Prong setting above round side diamonds totaling approx. 0.60 ct. Approx. 2.60 ct total.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

Choose your center weight and metal for this made-to-order ring.

Signora Jewels sets the 8.20 × 6.50 mm blue cushion above a line of larger round side diamonds rather than fine micro-pavé. The white rounds step away from the colored center on both shoulders, giving the engagement ring a strong contrast in both shape and color.

The Four-Prong basket rises approximately 7.0–7.5 mm and stays open beneath the center. At the base, the shank measures about 2.00 mm wide and 1.70 mm thick, while the diamond-set shoulders broaden near the cushion.

The larger shoulder diamonds give this ring a different rhythm from a fine pavé band. Each round reads as an individual stone, while the blue cushion stays clearly separate at the center.

About Lab Grown Diamonds

The cushion center combines softly rounded corners with a broad rectangular face, while the round shoulder stones add a tighter sparkle pattern beside it. Read more about diamond shapes and proportions in the diamond stone guide.

Metal, Care & Fit

White gold and platinum give the strongest contrast around the blue center and white side diamonds. Yellow and rose gold create a warmer frame around the colored center. Compare choices in the metal guide. Clean underneath the open gallery and around the shared-prong side stones with warm water, mild soap and a soft brush.

FAQ

How much diamond weight is set into the shoulders?
The round side diamonds total approximately 0.60 ct. The listing uses the supplied total weight without relying on an estimated stone count.

How is the blue cushion center held?
The center is secured by four prongs around its 8.20 × 6.50 mm reference outline. The open basket leaves the side profile of the cushion visible.

What makes this different from a fine pavé engagement ring?
The shoulder diamonds are substantially larger than micro-pavé stones and read individually from the front. That creates a stronger transition from the blue cushion into the band.

How high does the center sit?
The setting rises approximately 7.0–7.5 mm. That elevation separates the cushion from the shoulder diamonds and leaves accessible space underneath for cleaning.

Which metal gives the blue center the strongest contrast?
White gold and platinum create the clearest contrast around the blue cushion and white accents. Yellow and rose gold give the center a warmer surrounding tone.
