hello, found stone on beach, green translucent crystal inside, cannot identify, help please
From a quick first glance it looks most like prehnite. Can you post some more pictures? Also, where did you find it? The locality may be an indicator of what it may be...
Looks darker than most prehnite...looks more like jade.
It looks like it has a radiating internal structure which would indicate a greater liklihood of prehnite. However picture quality is poor and we don't have any locality information which would be crucial for identification.
