Believed by ancient peoples to actually contain fire, opal has the ability to flash an array of luminous colors when exposed to light. This fiery rainbow is produced by the diffraction of white light through a micro-structure of silica spheres, and each size sphere reflects light of a different wavelength. These stunning square clip-on earrings from Leon Nussbaum of London feature a matrix of iridescent white opal hand-set in sterling silver. Handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Dimensions - 0.5 inches squared.
