The link goes to a login page for SkyDrive. Can you upload it here or put it on a publicly accessible image sharing service such as http://imgur.com/ ?

It says "NolaMuller's images are not publicly available." In imgur, you need to make your album public.

Looks like Lepidolite Mica, most likely from Brazil or Maine.

I think that you are right. What I have found is that the "rock" is actually a section of core brought up from underground in a mine in Springbok in the Northern Cape in South Africa. I was amazed how messy it was for a rock - all the lepidolite (which is very thin and breaks off the "rock" ) was surprising to me. But I tried to pry a little loose and I found that it is in a very porous white mix - which is not solid rock. I can separate the purple mica into many rounds. I think that it has just been compacted into the core. Thanks for taking the time to come to my aid Hershel - I am just very interested in what I was given!
