What is this rock?

by Nicole
(Quebec Canada)

I have inherited my grand fathers rock and minéral collection, therefore I could not tell you where this one was found...it has a two tiered green layered body with an opal like cream colored splotch on top. It is smooth, has a green streak.

Nicole,

Sorry I don't know what you have. A scratch test will help you narrow the choices. See the hardness section of this page:
