Sapphire is next to diamond on the hardness scale. It is a beautiful and durable stone that comes in a wide variety of colours from red, yellow, green, and the traditional blue. Ruby is simply a specific colour of Sapphire.
I offer coloured sapphires from ethical mines in Australia and the USA. Each stone is hand selected for colour and comes with a fair trade level of background information about the stone so we can track its mining origins through to where it was cut, polished, and distributed.
