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.

At a glance

An oval lab grown diamond nature inspired engagement ring from Signora Jewels.

An approximately 1.50 ct oval brilliant measuring 9.35 × 6.43 × 3.99 mm is secured in a four-prong cathedral basket above a textured twisted vine shank with an open gallery.

Made to order in 11 metals: Silver, 9K/14K/18K Gold (Yellow, White and Rose) and Platinum.

Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.

The flowing vine shank wraps around the center like climbing branches before meeting beneath the basket. At Signora Jewels, the textured leaf-inspired finish gives the band depth without relying on accent diamonds, allowing the oval brilliant to remain the brightest point of the design.

The approximately 2.10 mm comfort-fit base provides a balanced feel, while the cathedral shoulders lift the center into view without making the ring bulky. An open basket beneath the diamond allows light to enter from below and makes routine cleaning simple.

FAQ

Does the textured vine band feel rough?
No. The leaf-inspired texture is carved into the surface while the inside of the comfort-fit shank remains smooth against the finger.

Why is the center raised in a cathedral setting?
The cathedral shoulders support the basket while lifting the oval diamond into stronger light. This also leaves room beneath the center for easy cleaning.

Can this ring be worn with a wedding band?
Yes. A slim straight band pairs well with the raised cathedral setting, while a contoured band follows the flowing vine profile more closely.

Which metal color best complements the vine design?
Yellow and rose gold emphasize the organic texture of the leaves and vines, while white gold and platinum create a brighter contrast around the oval diamond.
