Lapis lazuli gem

A Lapis lazuli gem is obtained from mining copper rocks or tin rocks with a dwarven army axe, and then cutting the uncut lapis lazuli with the dwarven army axe or a chisel. It can be used with Unfinished wooden brooch to create a lapis lazuli brooch. Combining the brooch and the stone grants the player 30 crafting experience.

Tobias Bronzearms, found outside of the Taverley mine, will buy this off players for 150 coins and sell it for 500 coins.
