Chatham laboratory-grown sapphires and rubies are corundum stones with identical optical properties and characteristics as natural stones. The color intensity of these beauties is equivalent to the highest priced natural stones available, but at a fraction of the price. Corundum is one of the hardest, most durable stones available with a Mohs hardness of 9. So, sapphires and rubies are easy to set and care for.
