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 ring can feel like it has a story before it is even worn, and this cushion lab grown diamond engagement ring brings that feeling through a soft square center, vintage side stones and delicate beaded detail along the shoulders.

The cushion center is held in four prongs so its broad flashes stay open to the light. On each side, round diamonds sit inside marquise-shaped leaf motifs, giving the band a romantic, heirloom-inspired rhythm without overwhelming the center stone.

Select your center size from 1 to 4.5 ct and choose from 11 metals. Your ring is then made to order around those choices, with the same side-stone pattern crafted into the finished piece.

About Lab Grown Diamonds

A cushion diamond has rounded corners and broad, soft flashes of light, giving the center stone a romantic look that pairs beautifully with vintage and side-stone designs.

Every Signora diamond is lab grown — chemically, physically and optically identical to a mined diamond and graded on the same 4C scale. The only difference is origin: a larger, cleaner stone for your budget, with documented origin and no mining footprint.

Metal, Care & Fit

Choose from Sterling Silver; 9K, 14K or 18K gold in yellow, white or rose; or Platinum. Sterling silver is bright and accessible, gold rises in richness from 9K to 18K, and platinum is naturally white, dense and hypoallergenic.

Order in your known ring size; most metals can be resized after purchase. Clean with warm water, mild soap and a soft brush, then pat dry. Remove before swimming, showering, lotion or perfume, and store separately to protect the polish and milgrain-style detail.

FAQ

Can I choose a different cushion center size?
Yes. This ring is customizable from 1 to 4.5 ct, and the setting is made to suit the center size you select. The photos show a cushion square center of approximately 2.65 ct.

What is the total diamond weight shown?
The ring shown has approximately 2.90 ct total diamond weight across 15 diamonds. That includes the 2.65 ct cushion center plus 14 round side diamonds totaling about 0.25 ct.

What makes this ring vintage-inspired?
The side stones are arranged in leaf-like stations with beaded milgrain-style edges, which gives the band an antique, crafted feel. The center still stays clean and prominent, so the ring reads romantic rather than overly ornate.

Are the side stones included with every center size?
Yes. The round side diamonds and vintage band design are included as shown. Only the center diamond size changes when you choose a different carat option.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are real diamonds with the same chemistry, hardness and sparkle as mined diamonds, and they are graded on the same 4C scale by independent labs such as IGI.

Can this ring be resized?
Most metal options can be resized after purchase, depending on the adjustment needed. Because the side-stone design extends along the shoulders, choose your known size carefully or contact us for sizing help before ordering.
