Abstract (en)
A decorative element (400) comprises a faceted (110, 140) decorative body (100) with a flat back surface (150), a microstructure on the flat back surface of the decorative body, the microstructure (200) comprising a faceted region, and an at least partially reflective layer (240) on at least a portion of the faceted region of the microstructure. The combination of the faceted region and the at least partially reflective layer is configured to reflect light incident on the at least partially reflective layer through the decorative body in multiple directions. Methods for manufacturing a decorative element and a faceted microstructure for improving the appearance of a flat-back decorative body are described.
