The Collection
Lab Grown Diamond Jewelry
Every diamond we set is grown, not mined. A lab-grown diamond has the same carbon crystal structure, the same hardness and the same fire as a stone pulled out of the ground — it is a diamond, graded on the identical 4C scale, simply made in weeks rather than over a billion years.
This is our full lab-grown diamond catalog in one place: engagement rings, wedding and anniversary bands, studs and hoops, pendants, tennis bracelets and necklaces.
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.

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
01Solid 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.
02Hand 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.
03Everyday 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.
04Sizing & 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.
