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.

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

As shown: a 2.00 ct, 10.50 × 7.00 mm oval center in a four-prong setting, with 24 marquise accents totaling approx. 0.720 ct;

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

Made to order — the price updates with your selection. Change the proportions, center size or shoulder layout through our custom jewelry service.

Signora Jewels sets the 10.50 × 7.00 mm oval above two open rows of marquise diamonds, with four prongs placed clear of the long sides so the center keeps its full outline.

The marquise accents turn outward along the split shoulders. Their pointed ends create a leaf-like rhythm, while the openings between the rows let the metal flex into a narrower lower shank instead of carrying full width around the finger.

From above, the shoulders widen the ring near the center. From the side, the raised basket leaves room for a wedding band to sit close beneath the oval.

The marquise layout does more than add sparkle. Each pointed stone pulls the eye outward from the oval, making the center look longer while keeping the shoulders open rather than forming a solid wall of diamonds.

About Lab Grown Diamonds

An oval brilliant carries round-style fire through an elongated outline. The marquise accents repeat that length in smaller pointed shapes, drawing light along the shoulders instead of stopping it at the center.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K has more strengthening alloy for daily wear, while 18K has higher gold content and richer color; compare them in the metal guide.

Order in your known US size. The upper shank spreads into two diamond-set rows, so accurate sizing helps keep the oval centered; use the ring size and fit guide. Clean with warm water, mild soap and a soft brush, then rinse and pat dry.

FAQ

Can I choose another center diamond size?
Yes. The oval center is available from 1 to 4.5 ct, and the basket and metal weight scale to the selected carat. The photographed configuration uses an approx. 2.00 ct center measuring 10.50 × 7.00 mm.

How many marquise diamonds are set into the shoulders?
The shoulders contain 24 marquise Lab Grown Diamond accents totaling approx. 0.720 ct. Each accent measures approximately 3.00 × 1.50 mm and sits in an open prong setting.

How is the oval center held?
The oval center is secured by four prongs placed around its rounded ends and sides. The open basket exposes the long edges to light and keeps the elongated outline clear from above.

Will a wedding band sit beside this engagement ring?
A straight wedding band sits close beneath the raised center basket, though the split shoulders can leave a small gap near the head. A gently contoured band gives the tightest fit.

What is the difference between marquise side stones and round pavé?
Marquise side stones create longer flashes and a pointed, leaf-like pattern across the shoulders. Round pavé forms a tighter continuous line, while this design leaves more open space between the accents.

What is the difference between 9K and 18K gold?
9K gold contains more strengthening alloy and has a harder surface, while 18K contains more gold and carries richer color. Both are solid gold choices for an engagement ring.

How do lab grown diamonds compare with mined diamonds?
Lab grown diamonds match mined diamonds in carbon structure, hardness and optical behavior; their origin is different. Signora Jewels supplies this ring only with Lab Grown Diamond stones.
