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 six-prong pavé engagement ring from Signora Jewels.

The reference center is a 1.50 ct round brilliant, approximately 7.3–7.4 mm across, secured by six prongs. Approximately 24–28 shoulder diamonds total 0.34 ct.

Made to order in 10K, 14K and 18K gold, available in yellow, white and rose gold.

Made to order in your chosen gold color and purity, with a round center from 1 to 4.5 ct.

Signora Jewels holds the 7.3–7.4 mm reference center with six polished claws arranged around the diamond's edge. There is no halo. Instead, approximately 24–28 small round diamonds run along both shoulders, adding 0.34 ct outside the center.

The lower shank measures approximately 2.30 mm wide and 2.00 mm thick. The diamond-set shoulders widen slightly to 2.30–2.50 mm before reaching the raised head.

About Lab Grown Diamonds

The round brilliant center uses a closely arranged facet pattern that returns flashes across its circular face. The shoulder diamonds are smaller round brilliants. Read our diamond stone guide to compare cut styles.

Metal, Care & Fit

Choose yellow, white or rose gold in 10K, 14K or 18K purity. The raised center needs clearance beside a companion band. Brush gently beneath the six prongs and between the small pavé stones, following our jewelry care guide.

FAQ

Why does this round center use six prongs?
Six polished claws hold the round diamond at spaced points around its edge. The additional contact points distribute support around the 7.3–7.4 mm reference center while leaving the faceted top visible.

Does this ring have a diamond halo?
No. The center sits in a Six-Prong Solitaire setting. Approximately 24–28 round accent diamonds run along the shoulders rather than surrounding the center.

How much diamond weight is in the pavé shoulders?
The shoulders contain approximately 0.34 ct of round brilliant diamonds. Combined with the 1.50 ct reference center, the ring has approximately 1.84 ct total diamond weight.

Will a straight wedding band sit flush beside this ring?
The reference setting height is approximately 6.8–7.3 mm, and the shoulders measure 2.30–2.50 mm wide. These dimensions do not establish clearance beneath the head, so compare the completed ring with the intended companion band.

How should I clean the six-prong head and pavé band?
Use warm water, mild soap and a soft brush around the six prongs and between the shoulder diamonds. Rinse thoroughly and pat dry without dragging fabric through the small settings.
