Uncut gem

An Uncut gem is a gem that hasn't been cut. You can get these from mining ores or random events. Uncut gems are also a frequent drop from a variety of monsters. Generally sapphires, emeralds, rubies or diamonds are dropped by monsters, or are given away at random events. Most of the time when you get gems, they will be uncut. This way, you can cut them to get Crafting experience.

Uncut gems can be mined from the gem rocks in the north-west corner of Shilo Village, Lunar Isle Mine and sometimes in Tai Bwo Wannai Cleanup minigame. Players can only mine from gem rocks on a member's world. It is also possible to loot gems from safes in Rogue's Den.

Uncut and cut gems can be purchased from, stolen from, or sold at a gem shop. They can be identified with a red gem icon on the World Map. There is one in Al-Kharid, one in Ardougne, one in the TzHaar City, and one in Falador.

 * It is possible to mine two uncut gems from one rock in one attempt, usually a sapphire and something else.
