These rare ornamental stones were had white markings that resembled frost over the base color of the stone. They were usually tumbled and polished to a beautiful glassy finish. A master lapidarist could cut the fragile stone in facets, such as in a polyhedron cut,[note 1] so that at each point where facets met, a "snowflake" of white "frost" appeared. A typical stone had a base value of 10 gp.
Frost agates were often enchanted to be luckstones. Low quality stones were treated like other agates: powdered for use in sleeping draughts and other potions. Frost agate in particular was useful when mixing potions together as it nearly always prevented an explosive or poisonous result.[note 2]
