Jade refers to an ornamental mineral, mostly known for its green varieties. It can refer to either of two different minerals: nephrite, a silicate of calcium and magnesium, or jadeite, a silicate of sodium and aluminium.
It was not until 1863 that French mineralogist, Alexis Damour, determined that what was referred to as “jade”, could in fact be one of two different minerals: either nephrite and jadeite.
Both nephrite and jadeite were used from prehistoric periods for hard stone carving. Jadeite has about the same hardness (between 6.0 and 7.0 Mohs hardness) as quartz, while nephrite is slightly softer (6.0 to 6.5) so can be worked with quartz or garnet sand, and polished with bamboo or even ground jade.. However nephrite is tougher – more resistant to breakage. Among the earliest known jade artifacts excavated from prehistoric sites are simple ornaments with bead, button, and tubular shapes. Additionally, jade was used for axe heads, knives, and other weapons, which can be delicately shaped.
