Abstract
Spacing of lattice for non-iridescent labradorite, blue-iridescent labradorite, green-iridescent labradorite and red-iridescent labradorite were determined with scanning probe electron microscope. Lattice spacing increases the dynamical trend for different kinds of labradorite, line non-iridescent labradorite (107,5 ± 10 nm), blue-iridescent labradorite (150 ± 10 nm), green-iridescent labradorite (196 ± 10 nm), red-iridescent (231 ± 10 nm). This trend let is state iridescent of these samples to be caused by interference of secondary order.
