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 can contain an uncut sapphire. Uncut sapphires may also be obtained whilst mining, chances to obtain one will improve when wearing an enchanted and charged Dragonstone Amulet. More efficient ways of obtaining them are through killing monsters, or mining gem rocks at Shilo Village after completion of the Shilo Village quest.
