A beautiful example of Olmec Maskette in greenstone. The bluish colour of this stone was immensely valued by Olmecs. Jadeite is a rare variety of greenstone, and most probably originated from the Motagua River valley in present-day Guatemala, the only known source of jadeite in ancient Mesoamerica. Jadeite is an extremely dense rock with a relative hardness value equivalent to or even greater than that of steel.

The size, as well as absence of suitable holes on the eyes or mouth for sight and breathing suggests that this mask was not made to be worn on the face. The presence of holes on the sides and on the ears nevertheless suggests a ritual use, perhaps as a pectoral, belt, or headdress component, or potentially a funerary use as grave good.
