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 oval Lab Grown Diamond marquise side-stone engagement ring from Signora Jewels.

The reference design pairs a 2.00 ct, 10.30 × 7.19 mm oval center in four prongs with six marquise accents totaling approx. 0.60 ct.

Made to order in 11 metals: silver, 9K, 14K or 18K yellow, white or rose gold, and platinum.

Made to order — the price updates with your center-diamond and metal selections. Read the engagement ring guide before choosing the center.

Signora Jewels sets the oval high enough for its full outline to stay visible, then runs three marquise diamonds down each shoulder. Their pointed ends lead the eye into the center instead of forming a heavy halo. The 10.30 × 7.19 mm oval is held by four rounded prongs, leaving the long sides open to light.

The marquise stones sit in graduated steps, so the ring narrows cleanly into the polished shank. That keeps the 2.60 ct reference layout broad across the finger without carrying its width all the way around the band. The open spaces between the side stones also make each marquise outline easy to read from above.

About Lab Grown Diamonds

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. The oval center returns broad flashes through its long body, while the marquise accents add shorter, sharper reflections along the shoulders.

Metal, Care & Fit

Choose silver, 9K, 14K or 18K yellow, white or rose gold, or platinum. The metal guide compares gold content, color, density and everyday wear.

Clean under the oval basket and between the marquise settings with warm water, mild soap and a soft brush. Remove the ring before lifting weights or handling fabric that can catch beneath exposed prongs.

FAQ

What diamond weight is shown in the photos?
The reference design has approximately 2.60 ct total diamond weight. It combines a 2.00 ct oval center with six marquise accents totaling approximately 0.60 ct.

Can I choose a different center-diamond size?
Yes, the oval center is available from 1 to 4.5 ct. The basket and marquise side-stone spacing are scaled to the selected center.

How many diamonds are in this ring?
The reference ring contains seven Lab Grown Diamonds. There is one oval center and three marquise accents on each shoulder.

Is this a three-stone ring?
No, this is a multi-stone side-stone ring. Six marquise diamonds form graduated rows beside the oval center rather than one large diamond on each side.

How high does the oval sit?
The oval sits in a raised four-prong basket. This leaves the side profile open and gives the marquise diamonds room to meet the center without covering its outline.

What is the difference between oval and marquise diamonds?
An oval diamond has a continuous curved outline, while a marquise diamond comes to a point at both ends. This design uses the marquise points to direct attention toward the oval center.

What is the difference between 9K and 18K gold?
9K gold contains less pure gold and uses a firmer alloy, while 18K gold has richer color and greater density. Signora Jewels offers both as solid-gold options.
