A s the weather becomes warmer and summer beckons, the view outside our garden windows have gone from the soft blush of spring to vivid colours on full display – the verdant growth of greenery, glorious clusters of hot-weather blooms, the dazzling sunlight as it reflects on water, and the endless blue of warm evening skies. Sotheby’s Fine Jewels auction embraces the arrival of summer with a magnificent array of gemstones and jewellery. The sale, open for bidding until 10 June, includes whimsical brooches and cufflinks, a selection of signed jewels by Graff, Fabergé and Cartier, plus classic jadeite and diamond pieces.
