Nephrite jade and jade jadeite, which before the 19th century were considered the same stone, are today two stones with distinct characteristics and value. Of the two varieties, jadeite is the hardest, the rarest and therefore the most precious. The refinement and healing and even magical properties that the Chinese attributed to this gem made it a stone of choice for making jewelry, ornaments and art objects.
The main deposits of nephrite jade are mainly found in China, Russia, New Zealand and Canada. Jadeite, on the other hand, is found mainly in the ancient lands of the Maya or Olmec civilizations in Guatemala, but also in Burma and Kazakhstan.

History of jade
The importance of this stone became so great that it was omnipresent at all levels of life in the Chinese Empire. It will be one of the symbols of power for the living and a stone of eternity that adorns the bodies of the dead.
This will greatly influence the perception we will have of jade because it will evoke in the collective imagination a glorious past steeped in the mysteries of the legendary imperial China.
Jade arrived in Europe around the 15th century, with the Portuguese colonization of some regions of the Celestial Empire and the return of the conquistadors from America with the jade treasures plundered by the Amerindians. The Spaniards gave it the name of piedra de ijada which literally means "stone for the pit". This name would be attributed to the healing powers that the Amerindians attributed to calculus to cure kidney problems.
