Greenstein & Co.

We are delighted to welcome Greenstein & Co. to The Royal Exchange.

Already an impressive destination for gemstone enthusiasts and jewellery lovers, this new boutique is a welcome addition to our suite of premier experts and artisans. A supplier of fine antique and contemporary pieces, the brand also specialises in precious gemstones and natural diamonds: indeed, founder Saul Greenstein holds a qualification to grade diamonds from the prestigious Gemmological Association of Great Britain (GEM-A), and is a member of the UK’s largest association of professional art and antiques dealers, LAPADA.

Its specialism in superior antique, vintage and Art Deco designs allows it to “source and design bespoke pieces” — creating something distinctive and unique. The brand also offers “jewellery and watch repairs, jewellery cleaning, valuations for insurance and estates and expert witness services,” as well as the opportunity to sell items.

“Established in 2001 at the Bond Street Antique Centre, Greenstein & CO. has made Mayfair our home for more than 20 years,” the brand explains. “During this time, we built lasting relationships with customers and collectors alike. As a family-run jewellery business, we have earned a reputation for integrity, attention to detail and excellent customer service.”

“Whatever your style, we look forward to welcoming you to our showroom,” the team invites you. Discover more about the brand — including more fabulous pieces like those shown above — here on its website.
