The Collection

Cushion Cut Lab Grown Diamond Engagement Rings

Square through the outline but rounded at every corner — the shape is named for exactly what it looks like, a pillow. Larger facets give a cushion cut broader, slower flashes of light than a round brilliant, which is why it reads as romantic and slightly antique.

Cushion cuts sit beautifully inside halos and hidden halos; you will find those here alongside solitaires, three-stone rings and pendants.

  • Lab-grown diamonds — chemically and optically identical to mined stones
  • Signora Jewelry Certificate with every piece; IGI report for centre diamonds of 0.50 ct and above
  • 11 metal options: recycled silver, 10K/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, 10K, 14K or 18K gold, or platinum, and arrives with a Signora Jewelry Certificate, plus an IGI grading report when the centre diamond is 0.50 ct or more.

The Signora promise

Made for you. Backed by us.

Thoughtful craftsmanship, clear proof and support that continues after delivery.

Made to Order

Independent Certification

Each approved individual lab-grown center or primary diamond of 0.50 ct or more includes an IGI grading report.

Import Duties

Signora prepays import duties and taxes for every destination available at checkout, so they are not charged again on delivery.

Eligible standard products have 30-day returns when unworn, unused and in their original condition.

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, 10K, 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.
