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.

This cushion lab grown diamond engagement ring pairs a softly rounded silhouette with a hidden halo that reveals itself only when the ring catches the light from the side. The result is a clean solitaire look from above with extra brilliance tucked beneath the center stone.

The 8.00 × 8.00 mm cushion center is secured in a classic four-prong setting that allows light to enter from multiple angles. A circle of accent diamonds sits discreetly beneath the center, creating a subtle glow without changing the solitaire profile.

Made to order in your choice of center size and metal, this design is crafted for someone who loves timeless simplicity with a thoughtful detail that feels personal and unexpected.

About Lab Grown Diamonds

A cushion's pillow outline and rounded corners give a softer, warmer glow, with larger facets that scatter light in broad flashes. It pairs naturally with vintage, halo, and double-halo designs and wears gently against the skin.

Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.

FAQ

Can I change the center stone size?
Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

What is a hidden halo?
A hidden halo is a circle of small diamonds placed beneath the center stone. It adds sparkle from side angles while preserving the clean solitaire appearance from above.

Which metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white or rose, and Platinum.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same 4C scale.

Will a lab grown diamond last?
Yes. Lab grown diamonds are a 10 on the Mohs hardness scale and are suitable for everyday wear for a lifetime.

Where do these diamonds come from?
They are lab grown, offering a traceable, documented origin.
