LONDON.- A spectacular and very rare American silver and enamelled 108 piece 'Lap Over Edge' flatware service, made around 1891 by Tiffany & Co. New York, sold for £334,200 at Bonhams two-day Silver and Objects of Vertu including Gold Boxes sale in London on Thursday 20 and Friday 21 October. It had been estimated at £40,000-60,000. The sale made a total of £1,109,870.

Cecile Shannon, Bonhams Silver specialist, said, 'This was a wonderful and very rare example of Tiffany’s ground-breaking ‘Lap Over Edge' design - the most innovative silver flatware the company ever produced. Made by hand to the most exacting standards this labour intensive, costly special-order service stands as an emblem of late 19th century American conspicuous consumption and the luxury of the Gilded Age. I am not surprised that it attracted such spirited bidding from collectors round the world, nor that it sold for such an impressive sum.”

The Tiffany 'Lap Over Edge' service is so named because the rolled silver handle edges are turned towards the back, or sometimes the front, making the edges thicker than the middles. Every individual item – fork, knife spoon, etc – incorporated a different design, giving a more random and unique appearance to the service as a whole.

Each piece in the service offered for sale was hand-made to the client’s precise specifications. It was, therefore, extremely costly to produce and although the identity of the client is unknown, he or she would have been very wealthy. Every piece was hand struck and hand worked with acid etching and engraving, the unique selling point being that every handle was hand-decorated with complex, multi-coloured champlevé enamelling. Realistic studies of all types of flowers and leaves, including daffodils, snowdrops, delphiniums, thistles, roses, lilacs and so on, (and sometimes geometric shapes), grace every handle. Each one embellished with jewel-like enamelling, painstakingly applied.

Other highlights of the two-day sale included:

• A Louis XV vari-coloured gold and enamelled oval snuff box by Jean-Joseph Barrière, Paris 1772. The box was previously in the Sir Michael Oppenheimer Collection, Jersey. Sold for £35,580 (estimate: £10,000-15,000).

• An 18 carat vari-coloured gold, enamelled and diamond box in the Fabergé style, retailed by Asprey, London 1988. This box was inspired by a Fabergé Imperial presentation snuff box and egg given to Tsar Nicholas II on his coronation in 1896. Sold for £24,225 (estimate: £12,000-18,000).

• A unique 18 carat gold beaker by Rod Kelly, London 2006. Although he had made several pieces in gold, this was Rod Kelly's first commissioned beaker to be made in 18 carat gold. Rod Kelly, a highly regarded master silversmith and goldsmith, is one of the country's leading chasers. This beaker shows his distinctive technique of low relief chasing. Sold for £20,400 (estimate: £12,000-18,000).

• A monumental American silver covered jug by Andrew Ellicott Warner, Baltimore circa 1845. This jug is particularly rare because of its large size. No other jug by the silversmith of similar capacity has been found. It is part of the collection of the Edmondson family of Baltimore who originally commissioned the silver pieces in the 19th century. Sold for £8,288 (estimate: £6,000-8,000).

• A collection of early spoons to include An Elizabeth I silver apostle spoon, The Master George Fabutt, London 1572, which sold for £7,012 (estimate: £3,000-4,000).
