Amethyst crystals

From Old School RuneScape Wiki
Jump to: navigation, search

Amethyst crystals are the highest level rock in Old School RuneScape, requiring 92 Mining to mine. They are located exclusively in the Mining Guild.

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 an additional amethyst before depleting.

Mining Info[edit | edit source]

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 glory amulet equipped: the probability grows from 1/256 to 1/86.[3]
