What is a Parti Sapphire?

Parti sapphires are a rare and completely natural mineral with a mix of two-three colours in the same stone, mainly blues, greens and yellows. These colours emulate the iridescence of peacock feathers and make for a very unusual engagement ring or an eye-catching piece of occasion jewellery.
