Members can use the Fletching skill to cut a sapphire into sapphire bolt tips at level 56 fletching. Cutting a sapphire into bolt tips grants the player 4 experience in the Fletching skill, producing 12 sapphire bolt tips.
With a Divination level of at least 26, 3 uncut sapphires may be transmuted into one uncut emerald, costing two bright energy, and yielding 5.7 Divination experience for a profit of -1,125 coins.
Prior to the introduction of the Grand Exchange, the examine text on uncut stones said 'This would be worth more if it was cut'. However after the Grand Exchange was introduced, such description no longer matched the actual market facts and thus this was changed.
Although formally released on 8 May2001, uncut gems were briefly obtainable following the 17 March 2001 cooking update, before the crafting skill was fully implemented.
Up to eight uncut sapphires can be mined within a cave found north-west of Rellekka during the Tale of the Muspahquest. These rocks will not respawn for the player once they've been mined.
