Brief historical context
The firm was founded in Paris in 1892 by the Lacloche brothers (Fernand, Léopold, Jules, and Jacques) and grew in the first decades of the twentieth century into a respected jewellery house with branches in Paris, London, Madrid, and Biarritz. In the interwar period, the house firmly positioned itself in art-deco: geometric compositions, platinum with calibré-cut coloured gemstones, Egyptomania after the opening of Tutankhamun's tomb (1922), and the well-known minaudières (rectangular evening bags made from a single piece of metal, which the firm also produced for third parties according to auction literature).
In 1931, the firm went bankrupt, partly as a result of the global economic crisis of 1929. Unlike Cartier, Van Cleef, and Boucheron, the house did not continue afterwards; what was later traded under related names falls outside the historical oeuvre. Everything the firm made as Lacloche Frères is therefore by definition from before 1931, a strict dating that the vintage market structurally incorporates.
