Uncut diamond detail

An Uncut diamond is a white gem used in Crafting. An uncut diamond can be cut by a player with 43 Crafting by using it with a chisel, granting 107.5 Crafting experience and making the uncut diamond into a diamond.


Uncut diamonds can be obtained in several ways. Players can get them randomly while mining ores, or as drops from monsters. With level 40 mining they can be obtained from gem rocks in various locations, generally with quest requirements. Uncut diamonds are also obtainable from caskets, as a tip from the Gnome Restaurant minigame, be randomly foraged by a magpie familiar, or be gained as a reward in the Columbarium when using a columbarium key on an alcove. They can also be obtained from looting Dorgesh-Kaan Rich Chests and Customs evidence files.

A single uncut diamond is a possible prize from Treasure Hunter. When choosing the option to convert this prize to coins, players receive 500 coins, which is 3,567 less than selling them on the Grand Exchange.

With 42 Divination, 3 uncut rubies can be transmuted into an uncut diamond using 2 sparkling energy.

Uncut diamonds may be sold to any of the gem shops throughout Gielinor. The TzHaar gem trader does not carry any uncut diamonds in inventory, but will sell one for 300 TokKul if they are in stock, which is very rare.

Members can also use the Fletching skill to cut a diamond into diamond bolt tips by using a chisel on a diamond at level 65 Fletching. Cutting a diamond into bolt tips grants the player 7 experience in the fletching skill and gives the player 12 diamond bolt tips.

With 58 Divination, 5 uncut diamonds can be transmuted to an uncut dragonstone using 2 gleaming energy.
