The big surprise is the enthusiasm of customers, even as prices notch up. The first key point is the £1,000 barrier, which many brands strive to meet: American designers frequently use 14-carat gold and many others take steps to offer value. ‘We are introducing nine-carat pieces set with diamonds, or contemporary, textured styles with coloured semiprecious stones,’ says Diane Hall, creative director of Dower & Hall. ‘They are designed for everyday wear by women who know what they want.’ Monica Vinader sets diamonds in silver, from £215 for a ring, as well as 18-carat gold (Baja bracelet, £950); Katie Hillier’s cute gold and diamond animal pendants now come in 14-carat gold, from £595. For some, the average female spend is higher — Carolina Bucci, known for her woven gold and silk bracelets (£550) and initial rings (£3,770), says, ‘The average female spend is up to £2,000 — what she might spend on a handbag,’ while Kiki McDonough, known for her bold mixes of coloured stones, says customers will spend ‘up to £4,000 for pieces they know will stand the test of time’. Most agree that beyond £5,000, other factors (often a consultation with a partner) enter the equation, but there are no rules. ‘The odd self-buy can be much more,’ says McDonough, while Reichmann says ‘a woman who regularly spends £3,000 on a dress will pay more than that for jewels’.
