An Uncut sapphire is a blue gem used in Crafting and Fletching. An uncut sapphire can be cut by a player with level 20 crafting by using it with a chisel, which makes the uncut sapphire into a sapphire and yields 50 crafting experience. Uncut sapphires can be obtained in several ways. Players can get them randomly while mining ores, as drops from monsters or as a reward from Random events. With level 40 mining and the quest Shilo Village completed, players can mine the gem rocks in Shilo Village. Gem rocks may also appear while playing the Tai Bwo Wannai Cleanup activity, where players can mine them 3 times. A quick way to get uncut sapphires is Wall safe cracking in the Rogues' Den, but this requires level 50 Thieving. Uncut sapphires can also be found in the King Black Dragon Lair. Uncut sapphires are also a common reward of the Gnome Restaurant activity and from Managing Miscellania. Also, uncut sapphires can be bought from the Gem Shop.
Members can use the Fletching skill to cut a sapphire into sapphire bolt tips by using a chisel on a 'cut' sapphire at level 56 fletching. Cutting a sapphire into bolt tips grants the player 4 experience in the fletching skill and gives the player 12 sapphire bolt tips.
