Hi Peter, not no be obnoxious but for the sake of scientific accuracy (and perhaps to put your mind at rest a bit)...several international agencies ...

Thank you Pete and thank you Alfredo, and apologies to Stoned for sounding snitty. Text is often emotionless and I missed the joke.

I can't tell whether you are serious or joking. I sincerely hope the latter. Again, where's the health hazard? It's a cobble that stinks like sulfur ...

Nice write-up on why we shouldn't eat our specimens, crush them and snort the powder, or rub them vigorously on skin (especially injured or broken skin)...with that I'm stepping off my eternal soapbox ...

Hi again Roger,

humans form bezoars too...but not ones made of apatite. :)

Is this discussion still going? I throw my hands (and my malachites) up in the air.

Good thing half my collection is quartz, nobody's screaming about silicosis from handling them. Not yet, anyway ...

Some bonus pictures: I tried to "infect" my son with the mineral passion by taking him to this crystal paradise ... he first seemed to have fun, but became bored rather quick ... maybe too y ...
