I think that all rocks are more dense than 1 lb/gallon.
P.S. The density of water is 8.3 lb/gal. The density of your rock is 1 lb/gal. There is no such rock, unless it is hollow. There are some very rare rocks that are less dense than water. But most are way more dense than water. That's why we say something "sank like a stone".
