There is a house in southern Minnesota on I35, newly east of the interstate that used to sell these big pink rocks. Does anyone know the entitle, address, phone number or a website for this place? I would like to buy one.
Answers:    It be probably quartz or granite. There is a place in Milford New Hampshire that have them. They are HUGE and a rosy pink. They had them wrinkled up the drive of the place. Some were as big as a sofa. Don't remember the first name of the place but you can probably contact one of the town departments at the below link and ask them the company given name. http://www.milfordnh.info
