Identity Help Pink crusted quartz from Brazil - help please

Hello
I was hoping to find out what this is?
I bought it from my wholesaler here in the UK, he wasn't too sure what it was.
It comes from Brazil - again, location not 100% confirmed but it is either Minas Gerais or Bahia.
Does it have a particular name at all?  Does anyone know?  Any help wold be appreciated.
Many thanks in advance

Hi Tanya.

That is a beautiful specimen.  I think it is all quartz.   But that pink is gorgeous!

I would agree.
Likely two different growths of quartz on the same specimen.

I also agree.  Quartz over quartz.  When I zoom in on the photo, there appears to be a "gap" between the large quartz crystal matrix and the "druzy" quartz overgrowth.  The presence of another mineral in this interface may be the source of the pink coloration.  An iron oxide is a possibility though could be something else.  So, in effect what you would have is colorless quartz over colorless quartz with the interface mineral color visible through the druzy coating imparting the pink. Nice specimen. Too bad you don't have the location (yet).

I'm going to get some close up pictures and try to find an exact location.

Everyone seems to have hit the nail on the head with the two generations of quartz; just wanted to pop in and say that this specimen is quite lovely!
