Amethyst geode

Amethyst geode
Biomes	Any Overworld biome
Consists of

An amethyst geode is a feature found in the underground of the Overworld. Amethyst geodes contain smooth basalt, calcite, and are the main source of amethyst items and blocks.

Generation

Amethyst geodes generate between Y=-58 and Y=30. Each chunk has a ¹⁄₂₄ chance to attempt to generate a geode.

Structure

The inside of a cracked amethyst geode.

Amethyst geodes consist of three layers: an outer layer of smooth basalt, a middle layer of calcite, and a hollow layer of primarily amethyst blocks, with 8.3% replaced by budding amethyst blocks instead. Amethyst crystals generate within the structure on budding amethyst. Geodes have a 95% chance of generating with a crack, exposing its inside. Caves, aquifers, and canyons may be overridden by geodes, and as such are often obstructed by them.

History

October 3, 2020					Amethyst geodes are shown at Minecraft Live 2020.
October 6, 2020					Cory Scheviak tweeted a screenshot where an updated amethyst geode was shown with budding amethyst and amethyst buds.
Java Edition
1.17		20w45a			Added amethyst geodes.
		20w46a			Changed textures of calcite, block of amethyst, and budding amethyst.
		20w48a			Changed textures of block of amethyst and budding amethyst, once again.
		21w08a			The tuff layer of amethyst geodes has been replaced with smooth basalt.
					Amethyst geodes can no longer generate fully in midair.
		21w19a			Amethyst geodes have been stated to be significantly rarer. However, they are still as common as before.
		21w20a			Amethyst geodes have now actually been made rarer, from 1 geode in 30 chunks to 1 geode in 53 chunks.
1.18		21w41a			Amethyst geodes no longer generate above Y=30.
					The rarity of amethyst geodes has been adjusted to match 1.17 levels.
Bedrock Edition
1.17.0		beta 1.17.0.50			Added amethyst geodes.
		beta 1.17.0.52			Amethyst geodes are now available without enabling experimental gameplay.
		beta 1.17.0.56			Amethyst geodes have now been made slightly rarer, from 1 geode in 48 chunks to 1 geode in 53 chunks.
1.18.0		beta 1.18.0.20			Amethyst geodes are now able to generate below Y=0.
		beta 1.18.0.21			Amethyst geodes no longer generate above Y=30.
					The rarity of amethyst geodes has been adjusted to match 1.17 levels.
