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 round lab grown diamond ring with the romance of a flower in full bloom, this design wraps its brilliant center in sculpted petals before opening into delicate marquise-set shoulders.

The polished floral halo is formed entirely in metal, creating bold curves around the center without competing with its sparkle. Four marquise diamonds—two on each side—follow the divided shoulders like pointed leaves, bringing light and movement into the botanical silhouette.

Shown with an approximately 2.07 ct center, the ring can be made with a round diamond from 1 to 4.5 ct. Its six-prong basket, floral frame and split shoulders are proportioned around your chosen stone before the ring is crafted to order.

The surrounding petals are the signature: rather than filling the halo with smaller stones, the polished metal curves around the center like a sculpted rose, allowing the round diamond to remain the brightest point.

About Lab Grown Diamonds

A round brilliant is cut with 57–58 facets engineered to return light toward the eye, producing the lively sparkle that makes it the most loved engagement-ring shape. The marquise side stones extend that brilliance into tapered, leaf-like outlines that complement the floral setting.

Every Signora diamond is lab grown—chemically, physically and optically identical to a mined diamond and graded on the same 4C scale. The difference is origin: grown rather than mined, with a documented source, no mining footprint and greater size or clarity available for the budget.

Metal, Care & Fit

Choose Sterling Silver, 9K, 14K or 18K gold in yellow, white or rose, or naturally white Platinum. The photographed design shows a yellow-gold floral frame with contrasting white-tone diamond prongs; a specific two-tone combination may be requested through our custom-design service.

Order in your known ring size; most metal options can be resized. The elevated flower and divided shoulders may leave a small space beside a straight wedding ring, so a curved or custom-contoured band will usually create the closest fit. Clean with warm water, mild soap and a soft brush, then pat dry and store separately.

FAQ

Can I change the center diamond size on this floral engagement ring?
Yes. Choose a round center from 1 to 4.5 ct, including the approximately 2.07 ct size shown. The six-prong basket and sculpted flower are adjusted to keep the setting balanced around your selected diamond.

Is the floral halo set with diamonds?
The flower surrounding the center is sculpted from polished metal rather than filled with small halo diamonds. This gives the ring a bold rose-like outline while keeping the round center visually open and dominant.

Where are the marquise diamonds positioned?
Four marquise diamonds sit along the split shoulders, with two stones on each side of the center. Their pointed outlines echo leaves growing away from the flower and add approximately 0.14 ct of side-stone sparkle.

What is the total diamond weight of the ring shown?
The pictured configuration contains approximately 2.21 ct across five lab grown diamonds. That total includes the approximately 2.07 ct round center and four marquise side stones totaling approximately 0.14 ct.

How is the center diamond secured?
The round center is held in a six-prong basket, providing six points of contact around the diamond. This arrangement complements the flower’s symmetry while allowing the stone to remain visible between the prongs.

Will this ring sit flush with a wedding band?
The raised floral setting provides some clearance, but the sculpted petals and split shoulders may create a small space beside a straight band. A curved or custom-contoured wedding ring will usually follow the flower more closely for a fitted bridal stack.
