Black brightening flakes which prevent fine pigment particles from agglomerating. When incorporated into a cosmetic preparation, coating material, or the like, the flakes enable the resultant composition not only to give a satisfactory use feeling, e.g., spreadability on the skin, without giving a grainy feeling or be satisfactorily spread on a substrate but also to have high hiding power and assume a beautiful color tone. The black brightening flakes comprise a metal oxide, as a base material, which is derived from colloidal metal oxide particles and 5 to 70% by mass black pigment dispersedly contained in the base material. The black brightening flakes have an average particle diameter of 3 to 500 mum, average thickness of 0.1 to 5 mum, and average aspect ratio of 5 to 300.
