Pearl pigments are used extensively in printing inks, cosmetics, automotive coatings, and crafts because of their gorgeous iridescent and shimmering characteristics.

Pearlescent pigments are widely used in decorative coatings to achieve a luxurious, shimmering finish that mimics the natural luster of pearls.

Pearl pigments, also known as mica-based pigments, are widely used to add a shimmering, metallic, or pearlescent effect to a variety of products, including paints, plastics, cosmetics, and coatings.
