Backes & Strauss claim to be the oldest diamond dealers in the world, and can trace their history back to 1789.
Backes & Strauss were converted into a limited liability company in 1886, under the style Backes & Strauss Ltd.
The first marks that were entered in connection with this business with the London Assay Office was on the 25th March 1878 and 26th January 1886, 'MS' (Max Strauss) contained within an oblong punch. Further marks were entered at the LAO on the 24th January 1881, 3rd January 1888, and 12th October 1889, these last three being 'SS' (Siegfried Strauss, the brother of Max Strauss) contained within an oblong punch.
It would appear that at some point in the 1890's Backes & Strauss Ltd. ceased being manufacturers of jewellery, to concentrate on the specialised business of dealers in diamonds and precious stones.
It was in 1892 that they first occupied the premises at 14-16, Holborn Viaduct, a location that they were to remain until the late 1960's/early 1970's when they removed to 19 & 21, Hatton Garden, London, and at the same time at 88 & 90, Vittoria Street, Birmingham.
Backes & Strauss are still in business today and are now located at 113a Jermyn Street, Mayfair, London, and at Chemin des Troiselles, 46, CH-1294 Genthod, Switzerland.
