LONDON.- Christie’s upcoming Russian Works of Art sale on 29 November 2010 will be led by an important jewelled vari-coloured gold and guilloché enamelled Imperial presentation snuff-box, marked Fabergé, with the workmaster’s mark of Henrik Wigström. It was presented to the Turkish diplomat, Turkhan Pasha (1846-1927), in December 1913 on behalf of Emperor Nicholas II probably to commemorate the end of his five year ambassadorship in St. Petersburg. In 1919 the snuff-box changed hands for the last time, when it was acquired by the family of the present owner. It will be offered with an estimate of £400,000-600,000. The firm of Fabergé was awarded the title of Court Jeweller in 1884 and became one of the main suppliers to the Cabinet of His Imperial Majesty. Only fifty-four presentation snuff-boxes set with a miniature of Nicholas II were ever presented by the Emperor. Of these, only nineteen were executed by Fabergé
