Gems | OSRS Index

Gems are valuable stones that are primarily used in Crafting. They can be obtained from Mining (either randomly while mining other ores or from gem rocks), as a frequent drop from a wide range of monsters via part of the rare drop table or occasionally given out as gifts from various random events. Many types of gems can be purchased or sold (or stolen) at gem shops, identified with a red gem icon on the map ().

While mining most ore rocks or Motherlode Mine ore veins, players have a 1/256 chance of receiving a gem instead of an ore; this does not deplete the ore rock.^[1] Wearing a charged amulet of glory (of any number of charges other than 0) increases this chance to 1/86; wearing one while mining gem rocks increases the speed at which they are mined. It may be worth noting that the gems found randomly whilst mining most ores do not grant any additional Mining experience. Mining gems from gem rocks, however, does grant experience.

Gems are received from most sources in an uncut state. With a sufficient Crafting level, uncut gems may be cut with a chisel. For the precious gems, this cutting always succeeds; for the semi-precious gems - opal, jade and red topaz - there is a chance that the gem will be smashed into a crushed gem (You mis-hit the chisel and smash the [gem type] into pieces!).

Successfully cut gems may be made into jewellery and enchanted with Magic, or they may be cut into bolt tips with Fletching.
