I was going through some of my rocks and found this. A woman came into my store years ago and gave it to me. She found it and thought I would like it. Don't have any idea what it is.
I would be considered a very "Clear Quartz" or maybe even so clear it could be a herkimer diamond.. However the "pink" you've referring to is not the crystal's actually color.. Moreover it from the rust deposits in and around or that which has seeped into the crystals makeup.
Clean it up some,soak it in iron out,it will take the rust stains off of it.Then take a pic away form anything it will gather color from.I pretty sure theres some pink in there.
I soak quartz crystals i dig up in iron out.Even though you cant see any deposits on them,theyre there.Use the stuff outside,the vapor it releases isnt pleasant,use rubber gloves.
