How well do you know your pink stones?

Can you tell which stone this is?

There was a question asked online the other day which got me to thinking.  Sometimes when we buy stones at a show, they may be mislabeled.  Sometimes this is on purpose, in order to command a higher price.  Sometimes it's through ignorance.  I can tell you right now that I have bought beads at shows that I know are mislabeled, but they were cheap and pretty, so didn't really care.  Maybe I should have cared, and shouldn't have bought, but there you have it.

So, how well do you know your stones?  Specifically, your pink stones.  There's a great deal of difference in the prices of these, so it would be worthwhile to learn the difference in the way they look:


Pink Quartz


Rhyolite




Rhodonite




Lepidolite





Rhodochrosite
