The Embrace bangles by Nirav Modi are one of the most recognisable designs of the house. Bringing together design, craftsmanship and clever engineering – as well as many, many diamonds – each bracelet is made up of hundreds of interlocking parts, all assembled to ensure that it expands with the ease of an elastic band. Each bangle takes up to 200 hours of work, making each one a miniature feat of artistic engineering. Available in yellow, white and rose gold, every inch of the metal is set with diamonds. Price is for yellow gold; £45,200 in white gold; £50,700 in pink gold.
