These Blue-John vases were particularly rare in France during the time of the Restoration and they attest to the anglomania in vogue in France at the first part of the 19th century. Blue-John, originally only from quarries in Derbyshire, England, was a British specialty that did not arrive in France until the early 19th century. This semi-precious stone was appreciated for its translucency and its amethyst colour. The famous British bronze-artist Matthew Boulton specialized in Blue-John objects mounted in gilt-bronze, such as pendulum clocks and candelabra.
Our pair of vases, however, remains very French due to the design of the bronze mounts: the children with fish tails on the handles are directly inspired by the models of Pierre Gouthière. A pair of vases with similar chasing and stone has been part of Eleanor Post Close and Antal Post de Bekessy Collections (Sotheby's, Paris, 19-20 December 2017, lot 623).
