Georg Jensen is known today for fine quality and distinctive, Art Nouveau jewellery to include brooches, rings, bangles, earrings and cuff-links. Founded in Copenhagen, Denmark and from 1904, Georg Jensen Jewellery pieces have been signed in a number of different ways and although he died in 1935, Georg Jensen's namesake company continues to produce pieces bearing his signature today.

If you are looking to buy Georg Jensen jewellery at auction, it is essential the following marks/stamps are present to give an indication of authenticity and age. The alignment and placement of these markings can vary.

Jensen Maker's Mark. From 1904 until present, approximately ten different Jensen maker's marks have been used. The current maker's mark uses 'GEORG' above 'JENSEN' within an oval dotted surround, not to be confused with some of Jensen's earlier maker's marks that resemble a very similar appearance. Other Jensen maker's marks include 'GI' or 'GJ'.

Grade Stamp '826S' was used on earlier pieces and indicates slightly lower grade of silver, used until around 1915 and followed by silver grade stamp '830S' until around 1927 when Jensen introduced '925S' for sterling silver. Quite often Jensen jewellery is also stamped 'sterling'.

Designer Marks Designers for Georg Jensen used their own marks. For example, designer Vivianna Torun Bulow-Hube (often known as 'Torun') – began working with Jensen from 1967 and would stamp her designs 'TORUN'. Other designers for Georg Jensen include Bent Gabrielsen and Henning Koppel. Designer marks are found alongside the Jensen Maker's Mark.

Design Number For example. '208' or '142A'.
