An Uncut sapphire is a raw gem that is used in the Crafting skill. At level 20 Crafting using a chisel on an Uncut Sapphire gives 50 crafting experience and a Sapphire. Sapphires can then be used to create sapphire jewellery. Sometimes a casket contains uncut sapphire. Uncut sapphires may also be obtained whilst mining, chances improve when wearing an enchanted Dragonstone Amulet. More efficient ways of obtaining them are through killing monsters, or better yet mining gem rocks at Shilo Village after completion of the Shilo Village.
