The presence of regularly stratified layers in an iridescent garnet, predicted by an optical study, is confirmed by electron microscopic observations. Analytical electron microscopy showed that the layer texture is composed of major Fe-rich lamellae and minor Al-rich ones. TEM and SEM observations suggest that the fine layer texture probably resulted from exsolution. A possible mechanism for producing the moiré-like texture is presented.
