Known for its intense red hue, the July birthstone – the ruby – has long been hailed for its romantic associations, with its crimson shade the universal colour for love and passion. In ancient India it was known as the ‘king of precious stones’, prized for its rarity, beauty and alleged mystical powers, while those in Medieval times maintained that the stones had the ability to bestow health, wisdom and wealth on whoever wore them. Today, the ruby holds its position as one of the world’s most sought-after gems, often adorning the tiaras and necklaces belonging to members of the Royal Family – most famously in the case of the Black Prince Ruby, which takes pride of place on the Imperial State Crown. Here, we’ve rounded up the most ravishing ruby jewellery pieces to celebrate July birthdays.
