Whether in ancient India, medieval Europe, or the Golden Age of Hollywood, different eras have coveted rubies not only for their hardness and durability, but also their associations with vitality and wealth. Virtually identical to sapphire in all properties except colour, ruby is a variety of the corundum mineral species.

While richly toned gems like garnet and spinel and are often mistaken for the stone, genuine rubies are far more rare and valuable.
