Identity HelpPink Mineral on Pumice

Any ideas what causes the pink coloration?
Cobalt or Manganese? Or could it be something else with it being volcanic?
Also has some tiny, most likely Quartz crystlals, in matrix.

However, we can't really help you unless you can tell us a few things, most important being where is it from? Do you know how to test for hardness? If its calcite, it would fizz if you put some vinegar on it, (edit: just don't put it on the main face of the specimen, try to see if you can break a little piece off to test)...
Just having images does us no good, unless its something really obvious like a good, well formed Quartz crystal... Many minerals can have similar optical and morphological properties and that is why we need further info to give you an informative answer...
