S. Greenstein & Co Ltd

S. Greenstein & Co is a family-owned business established in 2001 by Saul Greenstein and co-owned by him and his wife, Ifediba Nwokedi-Greenstein.

Saul comes from a family of jewellery merchants. Both Saul’s maternal and paternal grandparents were jewellers in South Africa. Saul, therefore, began learning about gems from a young age and developed an enduring interest in gemstones and jewellery.

Having honed his skills in stores in the UK and abroad, Saul specialises in the retail of diamond engagement jewellery. He is qualified by the prestigious Gemological Association of Great Britain (GEM-A) to grade diamonds. He has a BSC in retail management from Surrey University and an MBA from Hult International Business School.

After a long career in education and psychology, organising and curating TEDxEuston events in London until 2019, Ifediba joined the business in 2016.

Whether you know exactly what item of jewellery you are looking for or need some guidance, our experience and training, along with our strong customer focus and attention to detail, will ensure that you are in safe hands.

We also purchase jewellery and are very happy to give you a valuation after assessing your items. Please get in touch with us to find out more.

We have decided to sell only natural diamonds rather than lab-made stones. Many of the diamonds in our collection are supplied with certificates from the Gemological Institute of America (GIA), assuring you of their quality and authenticity.

Buying fine jewellery is a very personal decision and trust is at the heart of any purchase. Saul Greenstein & Co’s commitment to quality means customers will always have confidence they are acquiring one-off vintage and antique pieces that are authentic, elegant and timeless.

We will work with you to find treasured and timeless designs that will help you to stand out from the crowd at the best value for your money.

S. Greenstein & Co offers complimentary ring sizing to fit after purchase.

As the one-off pieces in our collection are in high demand, to avoid disappointment, please get in touch if there is anything, in particular, you would like to view in person.

We are happy to ship items all over the world.

We invite you to visit our shop at stand 321-322, Grays Antiques Market, in Mayfair, London, where you will receive a warm welcome and personal and friendly service. We also visit antique fairs nationwide several times a year.
