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.

Signora Jewels secures the diamond in this heart-cut engagement ring with four tapered claws and a V-shaped point prong. The cleft stays clear.

The approximately 0.80 ct heart measures about 6.0 × 6.30 mm and sits above a plain lower shank estimated at 1.60 mm wide.

Design highlights

One heart-cut center, approximately 0.80 ct and 6.0 × 6.30 mm
Solitaire setting with four claw prongs plus a V-shaped point prong
No metal crossing the cleft between the heart’s two lobes
Plain polished lower shank, estimated at 1.60 mm wide and 1.50 mm thick
No halo, side diamonds or diamond-set shoulders
Fixed center weight with 11 metal options

The V-shaped guard follows the bottom point rather than rounding it off with a metal bead. The upper claws sit to either side of the cleft.

About Lab Grown Diamonds

The single heart-cut lab grown diamond supplies the entire approximately 0.80 ct total, without halo or shoulder stones.

Metal, Care & Fit

Yellow and rose gold emphasize the five prongs; white metals reduce that contrast. Brush gently beside the V-shaped guard using the care guidance.

FAQ

What protects the point of this 6.0 × 6.30 mm heart?
A V-shaped metal prong covers the heart’s point, while four tapered claws hold the lobes and lower sides. Sections of the diamond’s edge remain exposed between the prongs. Remove the ring for lifting or activities that knock the setting.

Is the cleft between the heart’s two lobes covered by a prong?
The central cleft has no prong across it; the upper two claws sit on the lobes on either side. That leaves the notch visible instead of closing it with metal.

What should I check when stacking beside the heart’s V-shaped tip guard?
The V-shaped guard sits at the heart’s point, beyond the plain band’s outline. The estimated 1.60 mm lower-shank width does not establish clearance around that guard. Compare a companion band against the finished setting so it does not press on the prongs or diamond.

How should I clean where the V-shaped guard meets the heart?
The V-shaped prong wraps around the pointed end, while the four claw prongs meet the heart farther up its sides. Use warm water, mild soap and a soft brush around those metal-to-stone junctions, then rinse and pat dry. Do not push pointed tools beneath the guard or pull cloth under the claws.
