ID help is needed....

hey gang,
I live in Southern California and found this in a canyon and have no idea what it is. It's about the size of a softball, is green and appears to be in layers, like thin slate ( but I'm sure it's not slate ). If you can, please let me know what this. I thank you in advance...

Possably Serpentine in Mica-Schist ?

Muscovite Mica

Commonly found in granite pegmatites, such as you find in So. Cal.

The green, chromium rich variety is called "Fuchsite"

I have a big chunk of the violet colored variety called "Lepidolite"

My first impression of yours was that it looked like green tourmaline in the mica, but I don't know much about green tourmaline in So. Cal. I know that pink tourmaline is more common in So. Cal.

Nice looking specimen you have there!

Hard telling on value, as values on gems and specimen material seems to be going up and up. Off hand, I would scrub it a little and put a $15-$25 tag on it. Where you found one, there should be more, including other related minerals.

You have a nice display/conversation piece there! Congrats!

Hey I know that rock.

It looks a little bit like antigorite. I don't know if you guys have that out west or not.

@peg..

How easy does the stone flake off?.. It's it too easy to destroy.. then don't clean it.. However if it can be cleaned.. take a tooth brush and dawn foam.. and gently scrub out the dirt and mud.. or add 20 mule team to a buck of warm water and submerge the stone in the mixture for at least 24 hours.. and again more genital scrubbing with a tooth bush may be needed..

I'm just looking for some of the stones natural color, instead of looking past the mud or clay color..

An old post you guys found here. Upon a second look I'd rethink my answer to serpentine.
