Abstract: Described herein are compositions, kits and methods for polishing sapphire surfaces using compositions having colloidal aluminosilicate particles in an aqueous acidic solution. In some aspects, the methods for polishing a sapphire surface may include abrading a sapphire surface with a rotating polishing pad and a polishing composition. The polishing composition may include an amount of a colloidal aluminosilicate and may have a pH of about 2.0 to about 7.0.
