Rich and decadent, the ruby is often referred to as 'the King of precious stones', so it seems only right that they take pride of place at your proposal in the form of a ruby engagement ring.
Coming up trumps as the most durable gemstone (measuring nine out of 10 on the scale of mineral hardness), they also make the perfect choice for an engagement ring as they'll withstand everyday wear, giving you the opportunity to pass this special piece of jewellery down through generations.
Typically red in colour, rubies come in a wide range of differing shades, from striking scarlet and bright berry to soft pink and light coral, meaning they have lots of scope to suit all styles.
