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

A long hexagon step cut lab grown diamond engagement ring from Signora Jewels.

An approximately 1.50 ct long hexagon step cut diamond measuring 12.36 × 5.36 mm is secured in a four-prong cathedral open basket.

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 elongated hexagonal outline gives this solitaire a distinctive architectural presence while emphasizing clean, uninterrupted step facets. At Signora Jewels, four refined prongs secure the pointed ends and shoulders of the center stone while the cathedral basket gently elevates it above the shank. The open gallery allows light to reach the pavilion, enhancing the crisp mirror-like reflections unique to the step cut.

The approximately 1.90 mm comfort-fit shank keeps the ring balanced despite the elongated proportions of the center stone. With an approximate setting height of 6.80 mm, the cathedral profile creates an elegant side view while remaining comfortable for everyday wear.

FAQ

What makes a long hexagon step cut different from other elongated shapes?
Its pointed ends and long parallel facets create a bold architectural appearance with broad mirror-like reflections. The unique outline offers distinctive finger coverage while maintaining clean geometric symmetry.

Why is a cathedral basket used for this design?
The cathedral shoulders support the basket while lifting the center stone into stronger light. The open gallery beneath also makes routine cleaning easier.

Can this ring be worn with a wedding band?
Yes. The raised cathedral basket allows many straight wedding bands to sit close, while contoured bands can follow the profile more precisely.

Which metal color best complements a long hexagon step cut?
White gold and platinum emphasize the crisp geometric lines, while yellow and rose gold create warm contrast around the elongated center stone.
