About Us

Gardan Limited is Gary Djanogly and Dan Spiro.

Gary joined the jewellery trade in 1978, serving an apprenticeship in diamond sorting at Graff Diamonds Ltd. This training included buying diamonds and coloured stones on the local market, as well as working at the trade exhibition in Basel, Switzerland, and time spent learning the retail aspect of the business in the boutique in Knightsbridge. He has worked at the top level in the UK jewellery business ever since, representing some of the finest jewellery and watch marques in the World, including Piaget and Bulgari.


Dan has spent over 30 years in the design, import and distribution of watches, introducing the Raymond Weil collection to the UK, and being instrumental in setting up and presiding over one of the best watch distribution networks this country has ever seen. His experience and knowledge of the UK retail jewellery market has proved invaluable, and his opinions and expertise are still sought by many companies both here and abroad.


We source and sell diamonds in a variety of different cuts, weights, colours and qualities. We only buy from legitimate sources, who work within the framework as defined by the UN resolutions specifying avoidance of any potential rough diamond purchases which might fund drug dealing or terrorism. We carry a comprehensive stock of stones from 0.01ct to 5ct. Our larger stones, from half-carat sizes upward, are available both with and without certificates from the most respected diamond grading laboratories. Call our offices on 020 7404 4915 to enquire about any of your diamond requirements.
