Everyone knows that diamonds are forever. Less well known is the fact that the lotus flower is also an ancient symbol of eternity and purity. De Beers have united the two timeless icons in their new Enchanted Lotus collection, where delicate lotus flowers are woven into hearts with infinite threads of diamonds. We think the Enchanted Lotus band is especially stunning - with 1.41 carats worth of dazzling diamonds - and would make for the perfect expression of eternal commitment as a show-stopping wedding ring. £3,300 from www.debeers.com.
