Refuting "metaphysical" properties of rocks

Refuting "metaphysical" properties of rocks

In “refuting "metaphysical" properties of rocks” at:
http://lists.drizzle.com/pipermail/rockhounds_lists.drizzle.com/2013-November/002098.html
Kitty wrote:

“Can anyone direct me to a good source for refuting
"metaphysical" properties of rocks? I have a friend
who is very intelligent, but not especially well educated,
and he's all excited about something he heard about
"healing" gems. He's recovering from cancer surgery
and I'm afraid he may be thinking about using "treatment"
through crystals instead of further medical care. I don't
want to appear to laugh at him or "talk down" to him,
but I also don't want to just say, "we don't believe in
such stuff," and change the subject.”

I would suggest having him read:

G. Walton, Forbes Magazine, October 24, 2011

Quackwatch at http://www.quackwatch.com/

Of course there is nothing the prevents a person from
doing both regular medical treatments and “crystal
therapy” at the same time. That way your friend has
the benefits of medical science and, if nothing else, the
psychological comfort of having either a few pretty rocks,
gemstones, or fossils, to look at, meditate on, and think
about. Just do not get scammed by paying obscene
prices for rocks that are completely lacking in any
medical benefit as touted on the Internet.
