Superb quality 7.5cts of old cut diamonds pave set in platinum made by Hennell of London. 30mm x 27mm. The renowned firm of Hennell was founded by silversmith David Hennell (1712 – 1785) in 1736. During the 19th century the firm began branching into jewellery manufacturing, largely at the instigation of Robert’s son (also called Robert) who had joined the business. However, it was under the artistic direction of chief designer Charles Bruno during the 1920s and 30s that Hennell’s jewellery gained the recognition it deserved and in particular his Art Deco designs heralded a golden age for the firm in terms of jewellery.
