looks to be hydrothermal sulfide, copper rich ,if maybe you could show some more pics of the greenish,and the rusty orange matierial, we could better see the associative mins with the quartz. definatly cool piece tho.

it is a beautiful piece , looks like traces of iron and copper,common with sulfide deposits,there are other goodies found with with these sulphides, i would keep picking at the area you where got that,very cool ,i would like to hear some other opinions.

Yeah.. large combo stone.. which contains several types of minerals including white quartz.. But also looks like agate, feildspar and a few others.. great find.
