has suggested that this practice relates to a sixteenth century funerary ritual performed at the deaths of Pokom Maya lords: "When it appears then that some lord is dying, they had ready a precious stone which they placed at his mouth when he appeared to expire, in which they believe that they took the spirit, and on expiring, they very lightly rubbed his face with it. It takes the breath, soul or spirit."

The Maya also associated jade with the sun and the wind. Many Maya jade sculptures and figurines of the wind god have been discovered, as well as many others displaying breath and wind symbols. In addition, caches of four jade objects placed around a central element which have been found are believed to represent not only the cardinal directions, but the directional winds as well.

The aesthetic and religious significance of the various colors remains a source of controversy and speculation. The bright green varieties may have been identified with the young Maize God. The Olmec were fascinated with the unique blue jade of Guatemala and it played an important role in their rituals involving water sources. The Olmec used blue jade because it represented water, an Olmec iconography representing the Underworld. Blue also represented the blue color that snakes turn before shedding their skin; therefore, blue represents aquatic and serpentine rejuvenation.

, jade was the hardest mineral known to ancient Mesoamerica. In the absence of metal tools, ancient craftsmen used tools themselves made of jade, leather strops, string saws to cut and carve jade, and reeds or other hard materials to drill holes. (Mesoamerican artisans also used jade tools to work other stones.) It would take many hours of work to create even a single jade bead.
