Bob: That red crust is found on a lot of California jade . The jade has a high iron content so kind of rusts on the outside. Much of the jade from the area is also quite fibrous and contains crystalline inclusions. Jade should ring like a bell when whacked with a hammer and should be Mohs 6 or so. It usually won't scratch with a common nail. I'd guess your example may be nephrite jade of some sort.....Mel

In New Zealand, Jade (nephrite) is usually found in conjunction with asbestos, and it is not infrequent to find material like this that appears to be neither, and both at the same time although the material there has a yellow rind from weathering. Woody

The white on that looks like asbestos , the green looks earthy like the metamorphic rock called greenstone , a serpentinized basalt
