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.

Straight step facets give the emerald cut its unmistakable hall-of-mirrors appearance, while the trillion side diamonds angle toward the center to create a balanced three-stone silhouette. The polished shoulders remain clean, allowing the geometry of the diamonds to become the focal point.

The one-carat emerald cut center offers broad flashes of light rather than scattered sparkle, creating a refined appearance that pairs beautifully with the pointed trillion side stones. Together they produce approximately two carats of lab grown diamonds with excellent finger coverage while maintaining an elegant profile.

Every ring is individually crafted by Signora Jewels. Each diamond is carefully set, inspected and polished before shipment, producing a ring designed for everyday comfort and lasting beauty.

The combination of an emerald cut center and trillion side stones creates strong, clean lines across the finger. The pointed side diamonds naturally direct the eye toward the center stone while adding width without overwhelming the design.

About Lab Grown Diamonds

Emerald cut diamonds are prized for their long step facets and crisp reflections. Instead of intense sparkle, they produce broad flashes of light that emphasize clarity and symmetry, making this shape a favorite for refined engagement ring designs.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same international standards. You receive the beauty and durability of a real diamond with a documented origin and no mining footprint.

Metal, Care & Fit

Choose from Sterling Silver, 9K, 14K or 18K Gold in Yellow, White or Rose, or Platinum. Gold and platinum are naturally hypoallergenic and ideal for daily wear. Clean with warm water, mild soap and a soft brush, then dry with a lint-free cloth. Store your ring separately to maintain its high-polish finish.
