The jade stones come from alkaline magmas, after a long quimic and fisic terrestre process that takes approximately 400 millions of years, emerge from the interior of the earth-crust located in node forms that come to the surface on the mountains and alluvia sources, from where they fall in pebble forms to the mountain slopes where they are swept away by the waters of the rivers, giving them round forms.

The mineral familiy of the jade is made up by three stone varieties of metamorphic character, which are formed by silicates of Sodium –Na-, Aluminium –Al-, Calcium –Ca-, Iron –Fe-, and Magnesium –Mg-, with small quantities of Potassium –K-, Chlorine –Cl-, Fluorine –F-, Hydrogen –H-, Iodine –I-, Oxygen –O- and Manganese –Mn. The natural consistence of the jade stones in each of its varieties is compact, heavy and the colours go from a greenish white to a deep greenish black.

Due to its specific characteristics these stones have been classified minerologically as Jadeite, Nefrite and Cloromelanie.

The jade in its natural state, is generally associated to streamer and marble. All these stones are formed under natural conditions in the earth-crust by high pressures, which are due to the tectonical powers throughout millions of years.

400 000 000 years ago the Mesoamerican jade started to be formed in the depths of planet earth in the Devonian epoque of the Paleozoic era. The high temperatures of the subsoil and the tectonical pressures compressed and drove up those minerals to the surface of the earth, where this stone has been used as an object of spiritual and economic value for about 7 000 years.
