Uncut opal
An Uncut opal is a beige gem used in Crafting and Fletching. An uncut opal can be cut by a player with active membership and level 60 Crafting by using a Chisel on it, which makes the uncut opal into 15 opal bolt tips and gives you 480 Crafting experience.
Uncut opal can be obtained in several ways. Players can get them randomly while opening Caskets and Mining Ores, as well as a drop from certain Monsters.
