is a name applied to two different metamorphic rocks: Jadeite and Nephrite. Its name comes from the Spanish "piedra de ijada" or loin-stone, because it was believed by the Amerindians as a remedy for loin and kidney ailments, and thus placed on the body for such. Alternative spellings include "jaid" and "jadeite." "Nephrite" is derived from the Latin version of the Spanish words.
