JADE
Jade provides much scope for
confusion as there are two different stones both known as jade. One is Nephrite
jade, mainly from New Zealand, and is a deep opaque green often with black flecks.
It can be carved but is nowhere near as valuable as jadeite, the other stone
with the same name. 
This can occur in a range of colours
- white, lilac, brown, yellow, and the most valuable, a beautiful apple
green. It is an excellent stone for carving, and often a large part of its value
is in the quality of its carving.
