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 round lab grown diamond halo engagement ring from Signora Jewels.

A 0.80 ct round brilliant, approx. 5.9–6.0 mm, sits in a Four-Prong center inside a pavé halo of approx. 22 round diamonds; marquise-and-round shoulder diamonds bring the total to approx. 1.33 ct.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Made to order in your chosen metal with the fixed 0.80 ct center and the same halo-and-shoulder layout.

Signora Jewels builds this halo engagement ring around a 5.9–6.0 mm round center. Four rounded claws hold the diamond, then a tight row of small round stones traces the outside edge.

The shoulders do something different. Marquise diamonds alternate with round stones in an open shared-prong arrangement, so the band breaks into individual flashes instead of reading as one continuous pavé strip.

Shared-prong shoulder layout with open spaces between alternating shapes

The halo enlarges the outline around the center, but the shoulders keep moving outward with alternating marquise and round shapes. That combination gives the ring three distinct layers of light: center, halo, then the open diamond-set shoulders.

About Lab Grown Diamonds

The round brilliant center concentrates smaller reflections near the middle, while the marquise shoulder diamonds throw longer flashes along the band. Our diamond stone guide explains how different shapes handle light.

Metal, Care & Fit

The halo and shared-prong shoulders create more small spaces than a plain solitaire, so use a soft brush around the halo edge and between the marquise stones. Follow our jewelry care guide for routine cleaning.

FAQ

What does the halo do around the 0.80 ct round center?
The halo adds approximately 22 small round diamonds around the 5.9–6.0 mm center. It increases the visible diamond outline while keeping the center itself at approximately 0.80 ct.

How are the marquise diamonds arranged along the shoulders?
Approximately six marquise diamonds alternate with six round diamonds across both shoulders. Shared-prong metal holds the stones with open gaps between the shapes rather than forming a continuous channel.

How exposed is the round center in this halo setting?
Four prongs hold the center while the halo sits outside its edge. The diamond is not enclosed by metal, so avoid hard knocks to the exposed sections between the prongs.

Which part of this ring needs the most attention during cleaning?
The pavé halo and alternating shoulder stones create the smallest spaces on the ring. Brush gently behind the halo and between the marquise-and-round shoulder diamonds, then rinse thoroughly so residue does not remain around the shared prongs.

Can this halo ring be stacked with a straight band?
The diamond-set shoulders widen to approximately 3.0–3.5 mm near the center, and the halo is raised above them. A straight band’s final spacing depends on the finished side profile, so compare the two rings together before assuming a flush fit.
