Need help to identify rock with crystals inside

0 votes

I think it's possibly a lava rock and possibly quarts inside and there's some smokey crystals inside the clear one's. Can anyone tell me what this is? Found this in central Arizona. alt text

Looks like quartz but the picture is a little blurry can you get a closer picture of the crystals?

Put a drop of vinegar on a clean white part and see if it starts fizzing if it does not fizz then i would have to say its quartz with some iron/dirt stains. Very cool find!Looks like most of that rock is quartz and something just stained the outside of the rock.
