Our Business


As designers, manufacturers and wholesalers of fine diamond and gem set jewellery we work with a number of specialist retailers who want to offer their clientele exciting and stimulating products.

We maintain a stock of hundreds of items, of both original and traditional design, to cater for a variety of tastes and budgets. Working in 18 carat gold and platinum we aim to satisfy our customers’ desire for value and quality. We have a wide range of repeatable items; however, our greatest strength is in our collection of beautiful one-off pieces. Our buyers are able to purchase unique gems at competitive prices through our extensive network of gem dealers around the world.

Our History


PJ Watson is a traditional family business that has a pedigree spanning four generations.  Our roots go back to the reign of King George V and a very different Hatton Garden to the one of today. In each generation the business has been run by qualified gemmologists. It is one of our smaller claims to fame that we have the unique distinction of four generations of F.G.A.’s. Our experience and years of service to the industry enables us to cater for the needs of the most discerning of buyers.


Our Sources


Ours is truly a global business and our supplies come from around the world. The need to offer customers true value and not just discounted prices takes us as close to source as anyone can comfortably go.

We are, therefore, able to pass on these benefits to our customers. We are also conscientious about our buying and have strict best practice and fair-trade principles.


All the diamonds we sell are purchased from legitimate sources not involved in funding conflict and are in compliance with United Nations resolutions. We can therefore guarantee that our diamonds are conflict free, based on personal knowledge and / or written guarantees provided by our suppliers.
