The elongated Dutch marquise center is secured by a four-prong cathedral basket that protects the pointed ends while keeping the distinctive outline open to view. A hidden halo sits beneath the center stone, adding brilliance from side angles while preserving the uninterrupted profile of the marquise when viewed from above. The open gallery beneath the basket allows light to enter freely and makes routine cleaning easier.
The micro pavé shank carries a continuous row of round brilliant diamonds along both shoulders, drawing the eye naturally toward the center. The cathedral shoulders lift the setting elegantly while maintaining a balanced profile that is comfortable for everyday wear. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.

Why is a cathedral basket used?

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.
