Padparadscha is a very rare, pinkish orange sapphire. It is the only variety of corundum other than ruby that is given its own name, rather than being referred to as a sapphire of a particular colour. The name derives from a Sinhalese word, meaning lotus blossom.
Like all varieties of corundum padparadscha is an excellent jewellery stone, as it is second only to diamond in hardness.
