Jade is a tough metamorphic rock, generally of a green colour. In New Zealand it is generally called "Greenstone" or "nephrite". Pounamu in Maori.
It is highly valued for ornamentation, because of its toughness, it is not fragile.
It has been used as a replacement for steel as a edge material in a drill, and in a spokeshave.
The Maori were skilled in fashioning the material, and a piece of pounamu would be carried along with a piece of a grindstone, when on a journey. When the party stopped for a spell, the pounamu and the grindstone would be produced and some more work done on the shape. Quite similar to scrimshaw of the old sailors.
There are several varieties, including one Bowenite, which is almost transparent.
