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 marquise lab grown diamond engagement ring offers graceful length, brilliant sparkle, and a silhouette that stands apart from traditional shapes. This design showcases a beautifully elongated marquise diamond that creates an elegant finger-lengthening effect while maintaining a refined solitaire appearance.

Hidden beneath the center stone is a halo of round lab grown diamonds that adds brilliance from every angle. From the top, the ring appears clean and minimal; from the side, the hidden halo reveals a subtle circle of sparkle that enhances the center stone without overwhelming it.

Made to order in your preferred center size and precious metal, this ring combines timeless proportions with modern craftsmanship, creating a piece designed to celebrate a lifetime together.

About Lab Grown Diamonds

A marquise stretches weight across a long, pointed boat shape, so it presents one of the largest face-up sizes per carat. Its tapering ends draw the eye down the finger and create a distinctive, elegant look that feels both classic and unique.

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.

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 positioned beneath the center stone. It adds sparkle from side angles while maintaining the clean appearance of a solitaire 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.

Why choose a marquise diamond?
The elongated shape creates a larger face-up appearance per carat and visually lengthens the finger, making it one of the most flattering diamond shapes available.
