unknown rock

[rockpassion]

i have rediscovered this rock from a rock collector who had trown all his stones in his garden and i bought it from a woman who bought the house from the rock collector. Sadly where they are found is unknown. I have seen allot of rocks but this one i can't classify. It is not a gabbro or diabase but defently a plutonic rock. It has a strange brown crust which is very contrasting to the inside of the rock. If anyone knows what it is love to hear it.

Chlorite maybe? Just a guess. We need Clay Diggins back on the forum!! This is a pendant I made from chlorite.
