A rare, un-mounted, cushion-shaped diamond of fancy intense bluish-green, that weighs 3.64 carats, is estimated to sell for £220,000 – 250,000. Coloured diamonds are the rarest of all diamonds and the term “fancy” is used to describe a diamond of intense colour.

Bonhams will also be offering a selection of natural pearls, which are increasingly sought after by an international market. A pair of rare natural pearl and diamond pendent earrings are estimated to sell for A £40,000 – 60,000. The large pearl drops (12.95mm and 11.05mm) are suspended from a brilliant, single and baguette cut mount.

A further highlight is a natural pearl and diamond pendent and pair of earrings, all capped by rose-cut diamonds and a brilliant diamond surmount, are estimated to sell for £12,000 – 18,000.

Bonhams have also seen an increased demand for signed pieces by celebrated jewellery houses. Highlights within the Fine Jewellery sale include an art deco diamond bracelet by Lacloche Fréres, circa 1930 that is estimated to sell for £12,000 – 18,000. Also by Lacloche Fréres, circa 1925, is an unusual art deco sapphire, carved ruby and diamond brooch estimated to sell for £6,000 – 8,000.
