Sapphires are most commonly blue gemstones, although they can actually come in a range of different colours! Blue, pink, green, purple and orange sapphires can be found in a range of different shades, with the most vibrant stones being the more valuable. The rarest colour of sapphire is a beautiful deep orange colour, though it is not regularly seen.
The most expensive sapphire colour is pure blue, and vintage and antique sapphire rings most commonly feature blue sapphires, especially Art Deco sapphire rings in which the blue sapphire was a firm favourite.
