Amethyst crystals are the highest level rock in Old School RuneScape, requiring 92 Mining to mine. They are located exclusively in the Mining Guild with two areas to mine them from; the area directly west of the bank chest requires completion of the Elite Falador Diary (and having spoken to Belona for permission access), while the area further south-east has no additional requirements to mine.

When successfully mined by a player, they receive an amethyst, which yields 240 Mining experience. After being mined, amethyst usually takes around 75 seconds to respawn.

Wearing expert mining gloves while mining an amethyst crystal grants a 25% chance for the crystal to not deplete upon mining an amethyst, allowing you to mine additional amethyst before depleting. Note that wearing any other mining gloves does not affect its chance to deplete.

Pre roll drops[edit | edit source]

A gem table rolls before the main drop table.[1] There's a chance to receive nothing here so that players can receive no items from a rock even if they are guaranteed to receive an ore in the main drop table.[2] The table gets more likely to be rolled if the player has a charged amulet of glory equipped: the probability grows from 1/256 to 1/86.[3]

Main drops[edit | edit source]

The probability for a player to receive some amethyst drop depends on the player's mining level. The rock will deplete after receiving the amethyst, unless affected by the effect of expert mining gloves.

The chance of successfully mining an amethyst crystal varies from around 3.5% at level 92, scaling up to about 4.3% at level 99.[4] Bear in mind these rates likely do not take into account the invisible +7 Mining level boost enjoyed while inside the Mining Guild.

Changes[edit | edit source]

Date Changes
15 March 2023
(update | poll)
  • The object has been renamed from "Crystals" to "Amethyst crystals".
  • The "Prospect" option was removed.
3 November 2021

The permanently empty Amethyst vein in the Mining Guild has been replaced with a blank wall.

Trivia[edit | edit source]

  • Amethyst crystals are the only 'rock' in the game that can always have a chance at acquiring unidentified minerals, since they are unique to the Mining guild.
  • Unlike other rocks that have mining glove interactions, Amethyst crystals are only affected by one glove - the Expert glove. All other rocks that have mining glove interactions are affected by both the Expert gloves and either the standard mining glove or the superior mining glove, depending on ore type.
  • Prior to an update on the 3rd of November 2021 the northern part of the area that is accessible after the completion of the Falador diaries, contained an empty wall that never respawned any amethyst crystals but which could be interacted with.
