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 marquise lab grown diamond Tulip Basket engagement ring from Signora Jewels.

A 2.00 ct, 13.34 × 6.60 mm marquise center sits above engraved split shoulders with no accent diamonds. Approx. 2.00 ct total.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

Choose your center weight and metal for this made-to-order ring.

Signora Jewels sets the 13.34 × 6.60 mm marquise above a Tulip Basket, leaving the full pointed outline clear from end to end. The shoulders divide around an open center section, then carry engraved scroll and filigree work back toward the solid lower shank. No side diamonds interrupt the metal pattern.

The reference setting rises approximately 6.5–7.0 mm. At the base, the band measures about 1.80 mm wide and 1.60 mm thick, while the engraved shoulders spread to roughly 4.5–5.5 mm beside the center.

The engraving replaces the sparkle that would normally come from pavé. Fine scrolls fill the split shoulders while the marquise stays completely isolated in the middle, giving the engagement ring detail without adding another diamond shape.

About Lab Grown Diamonds

The reference marquise measures 13.34 mm from tip to tip, putting most of its visual spread along the finger. With no side stones beside it, the pointed outline stays uninterrupted. See the diamond stone guide for more on marquise proportions and cut.

Metal, Care & Fit

Yellow and rose gold make the engraved scrolls easier to read, while white gold and platinum put more visual emphasis on the center. Compare choices in the metal guide. Clean beneath the open basket and through the recessed engraving with warm water, mild soap and a soft brush.

FAQ

Does this ring have any side diamonds?
No. The marquise center is the only diamond; all shoulder decoration comes from engraved filigree and sculpted metalwork.

What does the Tulip Basket do for the marquise center?
The Tulip Basket lifts the center above the shoulders while leaving open space around its pavilion. That keeps the 13.34 × 6.60 mm reference marquise visible from both the front and side.

What makes the shoulders a Split Shank design?
The upper band separates into open sections beside the center instead of remaining one solid strip. Engraved scrollwork follows those divided shoulders before they rejoin the lower shank.

Will a straight wedding band sit completely flush?
The raised basket and divided shoulder structure can leave a small gap beside a straight band. A contoured band follows the center setting more closely.

How should the engraved filigree be cleaned?
Use a soft brush inside the recessed scrolls and beneath the open basket. Those carved areas collect more residue than the polished lower portion of the shank.
