The Collection

Marquise Lab Grown Diamond Engagement Rings

Pointed at both ends and full through the middle, the marquise spreads more surface area across the finger than any other shape — carat for carat, it simply looks the biggest. It is a dramatic, unmistakably vintage silhouette.

Our marquise designs run from single-stone engagement rings to fan clusters and side-stone settings where marquise accents flank a center stone.

  • Lab-grown diamonds — chemically and optically identical to mined stones
  • IGI certified, supplied with the piece on delivery
  • 11 metal options: recycled silver, 9K/14K/18K yellow, white and rose gold, and platinum
  • Made to order, so most designs can be scaled to your preferred carat weight

Every piece is made to order in your choice of recycled silver, 9K, 14K or 18K gold, or platinum, and arrives IGI certified with its lab-grown diamond grading report.

Made to last

Care & Composition

Clear information about materials, finishing, fit and everyday care — before you choose your piece.

  • Solid precious metals
  • Hand-finished in Surat
  • Made to order
Solid materials

Every Signora piece is made in solid precious metal — never plated or filled. Available options can include 925 sterling silver, 9K, 14K or 18K yellow, white or rose gold, and Pt950 platinum. Stone and certification details are listed on each product page.

Hand finishing

Each order is finished by hand in our family workshop in Surat. White gold is palladium-based, nickel-free and rhodium-finished; yellow and rose gold are polished to their natural warmth; platinum develops a soft patina with wear.

Everyday care

Wipe your piece after wear and store it separately in its pouch or box. Remove jewelry before swimming, showering, exercise or contact with lotions and cleaning products. For deeper cleaning, use lukewarm water, mild soap and a very soft brush; ask a jeweler to check stone settings periodically.

Sizing & Fit

Ring sizes and bracelet, necklace or chain lengths vary by design, so confirm the options on the product page before checkout. Because every piece is made to order, contact Client Care before ordering if you need a custom size or are unsure about fit.
