The blue bits reminded me of Azurite ...

I really don't remember where I found it. I was cleaning out my closet, and found a collection of rocks that I picked up when I was real little. I might have found it on the beach somewhere in California, because I remember picking up most of my rocks there. I'll try to get a clearer photo of it up. And thanks RD. Could it be like turqoise or something?

My fist thought was turquoise, but I'm more of a biologist than a geologist.

If this were found on a beach in the northern half of California I would say the blue is probably azurite. The vitreous luster and conchoidal fracturing makes it highly probable.

Now if the blue mineral is also rather soft - easily scratched with a knife - the probability is rather high it is azurite.

I found it in southern California, and I just tried scratching it with a knife and it didnt make a mark.

Woah... Thanks Bass.
It looks pretty much exactly like this.

Mine has a really glassy looking section though.

Grind it up melt the whole think (old way) or pass a huge electric current through it after`leaching the powder with sulfuric acid.

What about crystallization to isolate the mineral ?, (rather than electrolysis to extract the copper metal) ...
