‘Jade’, or ‘yu’, as it is called in China, is strictly speaking a generic term for two different Gems, Nephrite and Jadeite. The name is derived from the Spanish ‘Piedra de ijada’, loin-stone, jade having been recognised by the Amerindians as a remedy for kidney ailments. Because of its beneficial effect on the kidneys, the stone was also known as ‘lapis nephriticus’. That, indeed, is where the term ‘nephrite’ came from.
Chemistry:
Nephrite: Ca2(Mg,Fe)Si8O22(OH2).
Jadeite: Na(Al,Fe)Si2O6
