This oval Lab Grown Diamond engagement ring from Signora Jewels builds its shoulders from four small marquise cuts rather than pavé. The 8.25 × 6.25 mm center sits upright in four prongs, with two marquise diamonds stepping down on each side toward the polished band.
Each side stone points along the shank, so the setting reads as one continuous line across the finger. The oval returns quick, scattered flashes; the marquise accents answer with narrower points of light as the hand turns. At roughly 5.21 mm high, the open gallery gives the stones room for light beneath them. Browse more side-stone engagement rings.

The marquise stones are small enough to frame the oval rather than compete with it. Their pointed outlines carry the center into the band without adding a row of tiny pavé prongs.
About Lab Grown Diamonds
An oval brilliant carries round-style fire in an elongated outline that flatters the finger and gives a generous face-up spread. The marquise accents repeat that length in smaller pointed shapes along the shoulders.
Every diamond in this ring is lab grown, with the same carbon crystal structure, hardness and optical properties as a mined diamond. It is assessed using the same cut, color, clarity and carat standards.
Metal, Care & Fit
Sterling silver is bright and accessible. 9K, 14K and 18K gold increase in gold content and color richness, while platinum is naturally white and dense. Gold is available in yellow, white and rose.
Order in your known size or use the ring size and fit guide. Clean beneath the oval and between the marquise settings with warm water, mild soap and a soft brush. Have the prongs checked during routine professional inspections.
FAQ
Is the center diamond included in the price?
Yes, the price includes the approx. 1.00 ct oval center and all four marquise side diamonds. The complete ring has an approximate total diamond weight of 1.16 ct.
How large is the oval center diamond?
The oval measures approximately 8.25 × 6.25 mm and weighs about 1.00 ct. Its elongated outline gives the finger more visible length than a round diamond of comparable weight.
How are the marquise side stones arranged?
Four marquise diamonds are arranged as two graduated accents on each shoulder. Their pointed ends follow the shank and lead the eye back toward the oval center.
How high does the ring sit?
The setting rises approximately 5.21 mm from the finger. That open height leaves space beneath the stones for cleaning and light while keeping the five-stone arrangement compact.
What is the difference between a prong and bezel setting?
A prong setting leaves more of each diamond visible, while a bezel surrounds more of the edge with metal. This ring uses open prongs so the oval and four marquise outlines remain easy to see.
What is the difference between 9K and 18K gold?
9K gold has a lower pure-gold content and is harder for frequent wear, while 18K has richer color and a higher gold content. Both are solid gold and come in yellow, white and rose.
Can this ring be customized?
Yes, Signora Jewels can adjust the oval proportions, side-stone arrangement, setting or metal through the bespoke service. The listed version remains fixed at approximately 1.16 ct total.
