There are two types of Jade: Nephrite and Jadeite. The important property of all Jade is its toughness. Toughness in this context is the opposite of brittleness, and is a quite different property to hardness, which is simply resistance of a material to scratching. Diamond is the hardest substance in the world, but Jade is the toughest!
Because of its toughness, jade was used for axe heads and knife blades as well as for delicate, durable carvings.
The name Jade was derived from the Spanish Conquistadors term "piedra de ijada" or "colic stone". The term was coined when the natives were seen using the stone for kidney ailments.
