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 floral halo engagement ring from Signora Jewels.

The ring shown features a 6.40–6.50 mm round brilliant lab grown diamond weighing approximately 1.00 ct. Eight marquise diamonds and twenty round brilliant accent diamonds total approximately 0.27 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 four-prong cathedral basket lifts the round brilliant diamond above the finger while keeping the profile open beneath the center. Eight marquise diamonds surround the center in a floral arrangement, giving the halo petal-like definition instead of a continuous circle. As the ring turns, the marquise shapes catch the light from different angles and create a lively outline around the center.

Round brilliant accent diamonds continue between the marquise petals and along the shoulders, creating a balanced sparkle without distracting from the center diamond. The plain comfort shank keeps the profile clean while the cathedral shoulders provide support beneath the basket. Signora Jewels crafts every ring to order in your selected metal and center diamond size.

About Lab Grown Diamonds

The round brilliant cut is known for maximum light return and balanced sparkle. The floral halo surrounds the center with marquise and round accent diamonds, creating a soft botanical outline while preserving the brilliance of the round center.

Metal, Care & Fit

Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the cathedral basket and around the marquise halo with warm water, mild soap and a soft brush to keep every accent diamond bright.

FAQ

Why does this halo use marquise diamonds?
The marquise diamonds form petal-like shapes around the round center, giving the halo a floral appearance instead of a traditional circular border.

Can I choose a larger center diamond?
Yes. This design is available with center diamond sizes from 1 ct through 4.5 ct while maintaining the same floral halo style.

Does the cathedral basket make the ring taller?
The cathedral shoulders support the basket from beneath while keeping the gallery open, creating a balanced profile rather than unnecessary height.

How should I clean the floral halo?
Use warm water, mild soap and a soft brush around the marquise diamonds and beneath the center basket to remove everyday residue and maintain brilliance.
