A rare art deco black lacquer bangle, by Cartier, circa 1935 © 2002-2009 Bonhams 1793 Ltd

The sprung black lacquer cuff, applied to the front with three detachable diamond floral clips, set throughout with old brilliant, brilliant and single-cut diamonds, diamonds approximately 10.80 carats total, signed Cartier Paris, numbered, French assay marks, inner diameter 5.6cm. Sold for £96,000

Notes: In 1934, Cartier launched its black lacquer cuff bangle with detachable diamond clips. It was striking, sculptural, bold and modern; the purity of precious white diamonds juxtaposed with the stark black lacquer gloss was a masterpiece in monochrome simplicity and the jewel fast became a best selling line in London, Paris and New York.

The consummate skill and artistry of Chinese and Japanese lacquer work had been greatly admired in the West from the 17th century and Cartier successfully integrated this difficult technique with the taste for art deco. It was also a practical choice because when dry, lacquer is resistant to abrasion and damage by water and acid.

By mounting clips onto a bangle and thereby creating two jewels in one, Cartier 'fulfilled the trend for justifying a luxury article by its function' (Nadelhoffer, Cartier, 'Jewelers Extraordinary', London, 1984). Although the Wall Street Crash of 1929 had contributed to the worldwide financial slump of the 1930s, paradoxically this was also the decade in which Cartier created numerous masterpieces and these transformable jewels helped persuade the buyer that the expense was worthwhile. Customers could commission a bangle fitting to be designed around their existing clip jewels.

The bangle offered here is a rare survivor from this period of technical ingenuity and the epitome of late art deco style. The floral clips are similar in execution to a flower clip bangle created by special order by Cartier Paris in 1939 and now in the Cartier Collection.

A fine art deco onyx, coral, enamel and diamond penannular brooch, by Cartier, circa 1925 © 2002-2009 Bonhams 1793 Ltd

The open ended ridged coral hoop with enamel and single-cut diamond detail, terminating in a carved onyx bead each inlaid with a brilliant-cut diamond, to a cylindrical pin head set with single-cut diamonds in a cross formation with enamel detail, the later cone-shaped pin guard decorated with black enamel, signed Cartier and numbered, length 6.2cm. Sold for £45,600

Notes: Cartier unveiled jewels with daring colour combinations in 1925 at the Paris Exhibition. The most original and pronounced assortment, of which this brooch is a fine example, juxtaposed carved coral with diamonds and onyx. Some pieces additionally included emeralds. Previous years had seen simpler combinations, such as diamonds with onyx, sometimes with a hint of colour. Never before had such strongly contrasting colours been combined and expressed in a single piece of jewellery. The penannular brooch was a revival of the Iron Age Celtic design. Cartier redesigned it slightly by opening the ring, and using the sliding pin with bayonet clasp.
