Nephrite, a stone related to jade, found in several places in New Zealand's South Island. It is called pounamu<span> in Maori, greenstone in common New Zealand English.
A tiki is a traditional ornament that was made by the Maori people of the Pacific islands. These were the Polynesian first settlers of New Zealand. The tikis were made of a material known as nephrite. This is a type of stone closely related to jade. The material is difficult to work with, making the resulting tikis all the more unique and valuable.
