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 heart-cut lab grown diamond halo engagement ring from Signora Jewels.

One 1.03 ct heart center measuring 6.19 × 7.25 × 4.14 mm, with a protective point prong. Approximately 42–48 round accent diamonds total 0.48 ct. Approx. 1.51 ct overall.

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

Made to order in your selected gold color and purity, with a fixed 1.03 ct heart-cut center.

Signora Jewels frames the 1.03 ct heart-cut diamond with a single row of small round diamonds. Two rounded prongs hold the upper lobes, while a protective metal tip secures the point without hiding the heart's cleft.

The center measures 6.19 × 7.25 mm across. Approximately 22–26 diamonds trace the halo, and another 18–22 rounds continue along the shoulders. The polished shank narrows to 1.80 mm underneath.

Design highlights

1.03 ct heart-cut center · 6.19 × 7.25 × 4.14 mm
Single heart-shaped Halo with approximately 22–26 round diamonds
0.28 ct halo diamond weight
Approximately 18–22 round shoulder diamonds totaling 0.20 ct
Three visible securing prongs, including protective support at the heart point
Approximately 1.51 ct total diamond weight

The halo follows both rounded lobes before narrowing to the bottom point. Unlike a circular halo, its outline keeps the heart shape distinct, while the pavé shoulders carry the smaller diamonds into the band.

About Lab Grown Diamonds

The heart cut uses a central cleft and two curved lobes to create its outline. The surrounding round diamonds return smaller flashes along the border. Read our diamond stone guide for more about diamond shapes and faceting.

Metal, Care & Fit

Choose yellow, white or rose gold in 10K, 14K or 18K purity. The raised halo sits above the diamond-set shoulders, so check clearance when pairing another band. Explore our halo engagement rings and follow the jewelry care guide for cleaning the small pavé settings.

FAQ

How is the pointed end of the heart diamond protected?
A protective metal prong covers the bottom point, while two additional prongs support the upper lobes. The central cleft stays visible between them, preserving the heart outline.

How many diamonds surround the heart center?
Approximately 22–26 round brilliant diamonds form the single pavé halo, totaling 0.28 ct. The halo follows both upper lobes and narrows toward the bottom point.

How much diamond weight is in the halo and shoulders?
The halo contributes approximately 0.28 ct, and the shoulders add 0.20 ct. Together, the accent diamonds total 0.48 ct, bringing the complete ring to approximately 1.51 ct.

Can a straight wedding band sit flush beside this heart halo?
The setting height is estimated at 6.3–6.8 mm, while the pavé shoulders measure approximately 1.90–2.10 mm wide. These measurements do not guarantee a flush fit, so compare the completed setting with the intended wedding band.

How should I clean the small diamonds around the heart's cleft?
Use warm water, mild soap and a soft brush between the halo diamonds, especially around the upper cleft and pointed end. Rinse thoroughly and pat dry without pulling cloth through the small prongs.
