Bentonite clay is also rich in minerals like silica, calcium, magnesium, sodium, iron, and potassium. A good quality bentonite clay is grey or cream in color — steer clear of white "bentonite clay" (since it's likely not actually bentonite clay). It is very fine, has a velvet feel, is odorless and non-staining.
