One of the oldest and most widespread artistic expressions in Mesoamerica is the carving of hard stones. Different cultures produced pieces in jade, nephrite, turquoise, serpentine, obsidian, among others. Jade was the most precious element to the cultures of Mesoamerica until they knew and started working with gold in the Postclassic period (900 - 1521 AD). It is believed to have a symbolic value related to the sky, water, vegetation, life and fertility. This stone is found on the high plains, and it was brought to those regions that did not have it to produce ritual or funerary masks, various types of jewelry, human figurines and sculptures of animals or mythical creatures.
