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.

An Old European cut lab grown diamond vintage engagement ring from Signora Jewels.

An approximately 2.50 ct Old European cut round diamond measuring 8.40 mm is secured in a six-prong lotus basket above a vintage engraved milgrain shank with 20 round accent diamonds totaling approximately 0.08 ct.

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 Old European cut brings broad flashes of light and a softer faceting pattern than a modern round brilliant. At Signora Jewels, the six-prong lotus basket lifts the center above a finely engraved shank finished with delicate milgrain edges, giving the ring an unmistakable Art Deco character without overwhelming the diamond.

The approximately 2.00 mm comfort-fit shank feels balanced despite the larger center stone. Vintage engraving continues along the shoulders while twenty round accent diamonds add a subtle line of sparkle that complements rather than competes with the Old European cut.

FAQ

What makes an Old European cut different from a modern round brilliant?
An Old European cut has larger facets and broader flashes of light instead of the fine sparkle associated with modern round brilliant diamonds. Its proportions give the ring an authentic vintage appearance.

Why does this ring use a lotus basket?
The six-prong lotus basket supports the center diamond while creating a graceful floral profile beneath it. It also allows light to reach the pavilion through the open gallery.

Will the engraved band wear comfortably every day?
Yes. The engraving and milgrain are on the outside of the band, while the comfort-fit interior remains smooth against the finger.

Can this ring be paired with a wedding band?
Yes. The cathedral-style basket allows many straight wedding bands to sit close, while vintage-inspired bands create a matching heirloom look.
