Lot 46. A diamond plaque brooch, by Buccellati, circa 1939. Sold for £11,250 (€13,323). Photo: Bonhams

The lozenge-shaped panel of lace design, with a "tulle" ground overlaid by a pattern of old brilliant and rose-cut diamonds and similar border, with millegrain detail, mounted in platinum, principal diamond approximately 1.10 carats, remaining diamonds approximately 2.00 carats total, signed Buccellati, length 6.3cm

Note: This lot exhibits one of the most recognisable hallmarks of the House of Buccellati, the honeycomb 'lace' motif. The intricate pattern, individually cut by hand, lends an exquisite lightness to the jewel which, accompanied by diamond and floral accents, closely resembles a fragment of lace. From the opening of the first Buccellati shop in Milan in 1919, the family company has been reknowned for their mastery of the goldsmiths' art, using Renaissance techniques and executing jewels with the highest level of craftsmanship and creativity.
