Definition of skeletal crystal

Crystals that develop under conditions of rapid growth and high degrees of supersaturation so that atoms or ions are added more rapidly to edges and corners of growing crystals, resulting in branched 'dendrites' or hollow stepped depressions, 'hoppers'. Ice on windowpanes (frost) and pyrolusite on agate (moss agate) are dendrites, halite and gold may form hopper crystals.
