Lapis lazuli brooch

A Lapis lazuli brooch is a brooch received from using the Dwarven army axe. To make a brooch, mine either Copper rocks or Tin rocks with an army axe until you get an Uncut lapis lazuli, which can be cut into a Lapis lazuli gem with the Dwarven army axe or a chisel. Then chop regular Trees(or Evergreens), also with the axe, until you get a Wooden knot. Craft this into an Unfinished wooden brooch with the axe, and then attach the Lapis lazuli gem to it to get a Lapis lazuli brooch. The only stat bonus is Strength +1. It is tradeable, though it can not be sold on the Grand Exchange. Its value in the price-checker and when trading is 1250 coins. It is possible to obtain more than one of these at a time. It can be sold to a general store for 500 gp and the general store will sell it back for 1250 coins.
