Many of you believe that certain rocks contain certain properties. It's mostly shiny rocks (oh, but of course), but occasionally someone will claim that a rock with a lower refractory index has special properties, too.
Where I live, the ground is
full of rhyolite, a type of volcanic rock. Now then, some people do claim that rhyolite has special properties. (Usually, however, they're selling
Brazillian rhyolite, which is somewhat more colorful than the type I have.)
This page,
this page, and
this page all have something to say on rhyolite.
With that in mind, what do those of you who believe in the metaphysical properties of rocks suppose that the presence of so much rhyolite can or should do?
