An oval lab grown diamond vintage engagement ring from Signora Jewels.
An approximately 2.00 ct oval brilliant measuring 10.08 × 7.14 × 4.59 mm is secured in a four-prong cathedral basket with 18 marquise and round brilliant accent diamonds totaling approximately 0.14 ct.
Made to order in 11 metals: Silver, 9K/14K/18K Gold (Yellow, White and Rose) and Platinum.
Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.
The elongated oval brilliant is framed by an Art Deco-inspired infinity shank that flows gracefully toward the cathedral basket. At Signora Jewels, marquise and round accent diamonds are woven into the engraved shoulders with delicate milgrain edges, adding vintage character while allowing the center diamond to remain the focal point.
The approximately 2.10 mm comfort-fit shank balances the larger center stone without adding unnecessary bulk. The cathedral basket lifts the oval above an open gallery, allowing light to reach the pavilion while creating an elegant side profile that highlights the engraved details from every angle.

FAQ
What makes the infinity shank unique?
The flowing shoulders create a continuous looping design that symbolizes continuity while naturally drawing the eye toward the oval center diamond.
Why are both marquise and round accent diamonds used?
The combination creates a balanced vintage pattern inspired by Art Deco jewelry, adding texture and sparkle without overpowering the center stone.
Is the milgrain detailing purely decorative?
Yes. The fine beaded edges enhance the vintage appearance and highlight the engraved metalwork that frames the accent diamonds.
Can this ring be paired with a wedding band?
Yes. The cathedral basket allows many straight wedding bands to sit close, while vintage-style bands complement the engraved infinity shank and milgrain details.

Answers last updated August 2, 2026
When will my order ship?
Standard listed pieces are made to order with an estimated dispatch of 7 business days. Use the product-page estimate when it is more specific and the timing confirmed after ordering. Delivery timing begins after dispatch and varies by destination and carrier service. Fully custom commissions follow the production schedule confirmed with their approved specifications or CAD.
When is insured worldwide delivery free?
Orders of US$500 or more receive free express, insured and tracked worldwide delivery. Below US$500, express, insured and tracked worldwide delivery is charged at the fixed rate shown at checkout.
Will I have to pay import duties?
For every destination available at checkout, Signora prepays applicable import duties and import taxes. Customers should not be asked to pay those import charges again on delivery.
What certificate comes with my jewelry?
Every finished piece includes a Signora Jewelry Certificate. Each selected individual lab-grown center or primary diamond of 0.50 ct or above includes an IGI grading report. Below 0.50 ct, IGI can be arranged by custom request. Custom moissanite and gemstone selections include GRA documentation, with the exact scope confirmed in the approved specifications. The product page or approved specifications state the exact laboratory, report type and scope.
Can I return a made-to-order listed design?
Standard listed products are eligible for return within 30 days after carrier-recorded delivery when unworn, unused and in their original condition, with the original packaging and included documents. Normal listed choices such as metal, stone carat, chain or bracelet length, an extended ring size, or complimentary engraving do not by themselves make an item Final Sale. A sale or discount also does not imply Final Sale; only an item explicitly classified as Final Sale follows the non-returnable exclusion.
How are fully custom orders handled?
A fully custom commission is different from a listed made-to-order design. After its specifications or CAD are approved, a normal change-of-mind return does not apply. Manufacturing defects remain reviewable. Signora may accept an exceptional non-defect return case by case; documented labor and genuinely non-recoverable costs may be deducted, but these deductions are not a restocking fee.
