The elongated coffin cut center is secured by four prongs that leave its distinctive tapered outline fully visible. A closely fitted halo follows every angle of the stone, enhancing its bold geometry while preserving the dramatic silhouette. The elevated basket includes a hidden gallery beneath the center that allows additional light to enter and creates sparkle from side angles.
The double split shank opens gracefully beneath the halo, with rows of micro pavé diamonds extending across both shoulders before joining into a polished comfort band. This flowing structure gives the ring impressive finger coverage while keeping the center diamond as the primary focal point. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.

About Lab Grown Diamonds
The coffin cut combines bold geometric lines with an elongated profile for a striking modern appearance. The surrounding halo emphasizes its distinctive outline, while the hidden gallery and split pavé shank add brilliance from every viewing angle.
Metal, Care & Fit
Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the hidden gallery, around the halo and along the pavé split shank with warm water, mild soap and a soft brush to maintain maximum brilliance.
FAQ
What is the advantage of the hidden gallery?
The hidden gallery adds sparkle beneath the center stone while allowing extra light to enter the setting without changing the clean top view.
Can I choose a different center diamond size?
Yes. This design is available with center diamond options from 1 ct through 4.5 ct while maintaining the same halo and split shank design.
Why does the halo follow the coffin shape?
The custom halo mirrors every angle of the coffin cut, enhancing its distinctive silhouette instead of creating a traditional round outline.
Is the double split shank comfortable for everyday wear?
Yes. The split shoulders distribute the design evenly while the polished lower shank provides a comfortable fit for daily wear.

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.
