Jewelcrafting is a profession which was introduced in the Burning Crusade expansion. Players are able to make rings, trinkets, necklaces and statues, as well as cut gems for socketed items. Figurines are Jewelcrafter only items, and are a type of trinket that is Bind on Pickup. Special in Wrath of the Lich King are jewelcrafter only gems, which have stats bonuses that exceed the standard gems; they are varying cuts of dragon's eye and three jewelcrafter only gems may be equipped at one time.
Those who have not purchased the expansion are able to use items created by Jewelcrafting, although only those with the Burning Crusade are able to learn the Jewelcrafting profession itself.
Jewelcrafting also allows a player to cut gems recovered from mineral ores (copper, iron, mithril, etc) via Prospecting. Five pieces of ore are used up each time Prospecting is cast and the type and level of the gems prospected is dependent on the type of ore used as reagents.
Icy Prism and Brilliant Glass are two jewelcrafting recipes which combine lesser gems and reagents and create rarer gems.
