An uncut sapphire, the lowest level free-to-play gem
An uncut gem is cut into a gem using Crafting. Uncut gems are obtained from mining, bags full of gems, random events, minigame, gem shops, gem stalls, thieving, and as drops from monsters.
They can also be mined from gem rocks in the Shilo Village mine, Lunar Isle Mine, or from the Tai Bwo Wannai Cleanup minigame.
Gem shops, gem stalls, and thievable shop counters all have the icon on the World Map. They are in Al-Kharid, Ardougne, Mor Ul Rek, Falador, and Kourend Castle.
