That's why engagement rings with bright blue sapphires have long been a favourite for Royal weddings. Princess Diana's sapphire halo engagement ring famously brought out the blue in her eyes. Browse our collection of sapphire rings, from dainty silver rings to heirloom pieces. And if you're still crazy about her after all these years, celebrate your fifth or 45th wedding anniversary with a sapphire eternity ring. For a new twist on an old favourite, explore white, yellow or the ever-romantic pink sapphires. Be sure to complete the look with some other matching sapphire jewellery.
