Overview
Nephrite and jadeite[edit]
Nephrite and jadeite were used from prehistoric periods for hardstone carving. Jadeite has about the same hardness as quartz. Nephrite is slightly softer, but is tougher (more resistant to breakage) than jadeite. It was not until the 19th century that a French mineralogist determined that "jade" was in fact two different minerals.[citation needed]
