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-shaped diamond always carries meaning, and this design lets it stand on its own. A 6.50 × 6.50 mm heart lab grown diamond sits between two trillion side stones that taper neatly into the band, giving the center a wider presence without overwhelming its shape. Signora Jewels makes every ring to order in your chosen precious metal.

The heart is held securely with five prongs, including a protective V-prong at the point, while the trillion side diamonds add bright flashes from either side. The straight shoulders keep the profile balanced, making the ring comfortable enough for everyday wear while keeping every stone in clear view.

Design Highlights

Two trillion lab grown side diamonds
Approx. 1.39 ct total diamond weight
Five-prong center setting with protective V-prong
Three-stone engagement design

The trillion side stones mirror the curves of the heart while creating a clean transition into the band. From the top, the three diamonds read as one balanced composition instead of three separate stones.

About Lab Grown Diamonds

Heart-shaped diamonds combine brilliant faceting with a distinctive silhouette. Their carefully matched lobes and pointed tip create lively sparkle while preserving the recognizable heart outline from every angle.

Every lab grown diamond from Signora Jewels is chemically, physically and optically identical to a mined diamond and graded using the same 4C standards. The result is a real diamond with a documented origin and no mining footprint.

Metal, Care & Fit

Available in Sterling Silver, 9K, 14K and 18K yellow, white and rose gold, plus platinum. Order your regular ring size. Clean with warm water, mild soap and a soft brush, dry with a soft cloth, and store separately to help preserve the high-polish finish.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds have the same chemical composition, hardness and brilliance as mined diamonds and are graded using the same international standards.

Why choose a heart-shaped diamond?
