This is a specimen of baby blue-toned botryoidal gibbsite, a fairly uncommon aluminum hydroxide mineral that has been coming out of China over the last several years. Surprisingly lightweight! Gibbsite is normally thought of as a non-descript mineral in bauxite and is the actual ore mineral of aluminum in bauxite!
