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.

At a glance

An emerald cut lab grown diamond three-stone engagement ring from Signora Jewels.

The ring shown features an 8.50 × 6.30 mm emerald cut lab grown diamond weighing approximately 2.00 ct. Two tapered baguette side diamonds and eight round brilliant shoulder diamonds add approximately 0.24 ct.

Made to order in 11 metals: Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum.

Select your preferred center diamond size and precious metal using the options on this page.

The emerald cut center is held by four corner prongs that leave the long step-cut facets fully visible from above. Its open basket allows light to reach the pavilion while making the underside easy to clean. The elongated silhouette remains the focus because the side stones sit slightly lower than the center.

The tapered baguette diamonds narrow toward the band, creating a clean transition into the slim comfort shank. Four round brilliant diamonds on each shoulder add a subtle line of sparkle without interrupting the crisp geometry of the emerald cut. Signora Jewels makes every ring to order in your selected precious metal and center size.

About Lab Grown Diamonds

The emerald cut is known for its long step-cut facets that produce broad flashes of light rather than scattered sparkle. The tapered baguette side diamonds continue the clean architectural lines of the center while preserving the balanced proportions of the three-stone design.

Metal, Care & Fit

Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the basket and around the tapered baguette settings with warm water, mild soap and a soft brush to keep every facet bright and free from residue.

FAQ

Why are tapered baguette diamonds used on this design?
The tapered baguettes narrow toward the band, creating a smooth transition from the larger emerald center without distracting from its step-cut pattern.

Can I choose a different center diamond size?
Yes. This design is available with center diamond options from 1 ct through 4.5 ct while maintaining the same three-stone style.

Does the basket setting make cleaning easier?
Yes. The open basket provides access beneath the center diamond, making routine cleaning with a soft brush much easier.

Is the plain comfort shank suitable for everyday wear?
Yes. The slim polished shank balances the larger center while remaining comfortable for daily wear and stacking with many wedding bands.
