Gem rocks can be mined through the Mining skill. A Mining level of 40 is required to mine gem rocks, granting 65 Mining experience per gem.

Normal gem rocks can be mined in Shilo Village after a player has completed the Shilo Village quest or in the Lunar Isle mine after Lunar Diplomacy. The rocks regenerate 99 ticks (59.4 seconds) after being mined. Wearing a charged amulet of glory triples the success rate of mining these gem rocks. There is also another kind of gem rock which randomly appears during the Tai Bwo Wannai Cleanup minigame with a 5% chance per event. These rocks can be mined three times before they despawn.

The Shilo Village mine in the north-west part of the village has two sections: overground and underground. The underground section is only available for players who have completed Medium Karamja Diary, and it includes significantly more gem rocks than on the surface as well as a Bank Deposit Chest. For those who can only access the gem rocks on the surface, using a gem bag can extend trips.

Mining enhancers do not work on Gem Rocks, however wearing either a Celestial ring or Celestial signet will slightly improve mining success rate due their passive Mining boosts.

Gem rates

When a gem rock is mined, one of the following gems is produced:

	Item	Quantity	Rarity	Price	High Alch
	Uncut opal	1	60/128	390	12
	Uncut jade	1	30/128	127	18
	Uncut red topaz	1	15/128	2,765	24
	Uncut sapphire	1	9/128	238	15
	Uncut emerald	1	5/128	463	30
	Uncut ruby	1	5/128	988	60
	Uncut diamond	1	4/128	2,142	120

Taking this into consideration, mining a gem rock is worth 0 on average.

The probability for a player to receive a gem drop is shown for varying levels in the figure below. The rock will deplete after receiving the gem. Mining gloves and its variants do not affect gem rock depletion. Wearing a charged amulet of glory will significantly increase the chance of mining the rock.

Trivia

• When a gem rock is mined, the experience lamp sound will play. This is also the same sound as when a gem is mined from a normal ore rock.
• Gem rocks do not access the gem pre-roll table that provides gems from normal ore rocks.
