cauliflower-shaped rock some type of quartz?

Hi, my first post so I don't know if I will be able to attach a picture or not but here is a description of a rock I dug up in our yard in centeral Indiana. It is about the size of a cantaloupe. It seems very heavy for its size, almost 20 lbs. It literally looks like a petrified head of cauliflower. The "florets" appear to be be built up by layers of a semi-translucent milky-white crystal. It is very hard, scratches glass. I could not scratch it with a nail, but it did sharpen the nail quite well. It is fairly roundish, with the lumpy structures distributed evenly all around. Thanks in advance for any information, hope I can put a picture up.
