An independent IGI grading report is included when the selected individual lab-grown center diamond is 1.00 ct or larger. Its report number is laser-inscribed on that report-bearing center diamond. Accent and side diamonds are matched and inspected to Signora Standards and are not individually laboratory graded.

At a glance
A Dutch Marquise lab grown diamond halo engagement ring from Signora Jewels.
An approximately 1.50 ct Dutch Marquise center measuring 11.71 × 5.73 mm sits in a six-prong open gallery, framed by 26 round diamonds totaling approximately 0.14 ct.
Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.
Each metal color is shown in the photos. Choose your preferred center diamond size and metal from the options on this page.
The long Dutch Marquise center gives this Signora Jewels engagement ring a striking finger-lengthening shape, while the halo follows every point of the outline instead of looking round from a distance. Six prongs secure the center and leave the sides open so light reaches the diamond from more than one direction.
The comfort-fit shank measures about 1.75 mm wide at the base, keeping the ring light on the hand while giving the center stone visual presence. The open gallery also makes routine cleaning underneath the center much easier.
Design highlights
- Customizable Dutch Marquise center from 1 ct to 4.5 ct
- 26 round halo diamonds totaling approximately 0.14 ct
- Six-prong halo head with open gallery
- Plain comfort-fit shank approximately 1.75 mm wide
- High polish finish
- Made to order in 11 precious metal options
The halo closely follows the Dutch Marquise outline instead of creating extra width around it. From across the room the eye reads one larger diamond, while up close the fine round accents create crisp sparkle around every point.

About Lab Grown Diamonds
The elongated Dutch Marquise cut combines bright reflections through the center with pointed ends that emphasize its distinctive outline. Every diamond is F color, VS1 clarity and , then matched to the selected setting size for balanced proportions.
Metal, Care & Fit
Available in silver, 9K, 14K and 18K yellow, white or rose gold, plus platinum. Clean the ring with warm water, mild soap and a soft brush, paying extra attention beneath the open gallery where everyday residue naturally gathers.
FAQ
Will the pointed ends catch during daily wear?
The six-prong head protects the pointed ends while keeping the outline open. Normal daily wear is comfortable, although removing the ring for heavy manual work is always recommended.
Why does the halo make the center look larger?
Twenty-six small round diamonds trace the full Dutch Marquise outline instead of competing with it. Your eye reads a larger overall silhouette while the center remains the focus.
Can I wear a wedding band beside this ring?
The open gallery allows many straight bands to sit close, although a contoured band follows the halo outline most closely.
Which metal color suits this design best?
White gold emphasizes the crisp outline of the halo, yellow gold creates stronger contrast around the center, and rose gold gives the design a warmer appearance without changing the diamond color.

Answers last updated July 31, 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 express shipping free?
The configured free-shipping reference is orders over $500 USD. Eligibility, any currency equivalent, the available service and the final shipping charge are determined by the cart and Shopify checkout for your destination and order total before payment.
Will I have to pay import duties?
Duties and applicable import taxes are prepaid by Signora for deliveries to the US, UK and Canada. You should not be asked to pay them again on delivery.
What certificate comes with my jewelry?
Every finished Signora jewelry product includes a Signora Jewelry Certificate. Any independent stone report included with the selected configuration is shown in the product details and order record.
Can I return a made-to-order listed design?
Standard listed products are eligible for return within 30 days of 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 are still handled, and Signora will review any exceptional circumstances with the customer.
