A pair of gold, emerald and pearl earrings, signed Sah, circa 1935-40. Photo: Bonhams.

Each fancy-shaped textured gold plaque set with two bouton pearls and a border of step-cut emeralds in box-collet settings, suspending a fringe of seed pearls, one signed Sah, pearls untested, later hook fittings, length 5.2cm. Estimate £3,000 - 5,000 (€3,600 - 6,100)

The shaped plaques have been assessed by the London assay office and verbally confirmed to be of 22 carat yellow gold.

These earrings belonged to the vendor's aunt, a Londoner and scriptwriter for the BBC in the mid 20th century, and have always been known in the family as the "mutton chop" earrings. They are attributable to British avant-garde jeweller Sah Oved (1900-1983) who created some of the most original and striking jewellery designs in Britain before World War Two. Before 1938, the majority of Sah's private commissions were made in her husband's (Mosheh Oved's) shop, Cameo Corner, in Museum Street, Bloomsbury, which boasted a varied clientele of collectors, intellectuals, artists and royalty. Sah's jewels are distinguised by her use of high-carat gold - usually 22 carat - that display an impressive range of techniques and a smattering of gemstones. She rarely signed her pieces but on a very few occasions she did, simply with her name in a plaque.
