Amethyst buds are the first three stages of growth of amethyst clusters, which grow on budding amethyst.

Amethyst clusters are the fourth and final growth stage of amethyst buds, which drop amethyst shards when mined.

Obtaining

Breaking

The amethyst cluster block drops itself in any of its growth stages (rather than its amethyst shard drops) when mining it with any tool with the Silk Touch enchantment.

When mined without Silk Touch or broken by being pushed off an attached block by a piston or sticky piston, only fully grown amethyst clusters drop amethyst shards, while amethyst buds drop nothing. Breaking an amethyst cluster with a pickaxe drops 4 shards while any other method of breaking it yields 2 shards. The maximum amount of amethyst shards dropped can be increased with Fortune; Fortune I gives a ¹⁄₃ chance for 8 shards (averaging 5.33 shards), Fortune II gives a 25% chance (each) to give 8 or 12 shards (averaging 7 shards), and Fortune III gives a 20% chance (each) to give 8, 12, or 16 shards (averaging 8.8 shards).

Natural generation

Amethyst buds and clusters generate naturally as part of amethyst geodes, on exposed faces of budding amethysts.

Post-generation

Every time a budding amethyst block receives a random tick, there is a 20% chance for a small amethyst bud to generate on any of its sides, as long as the block being replaced with the small amethyst bud is air or a water source block.

Usage

Growing

An amethyst bud placed on a budding amethyst (rather than any other block) regardless whether it was placed by the player or spawned by the budding amethyst itself, grows over time, going through three growth stages – small, medium, and large – before reaching its 4th and final growth stage as an amethyst cluster, which drops amethyst shards when mined.

In Java Edition, the below logic can be applied:

1. Per random tick, updates occur to any given block in the loaded chunk every 68.27 seconds on average if the chunk center is within 128 blocks of a player's location.
2. Each random tick assigned to the budding amethyst block has a 20% chance of triggering an update on a budding amethyst block. Thus, it takes 5 random ticks on average for a budding amethyst block to grow one of its faces by 1 stage.
3. Of the 6 faces on an budding amethyst block, only one side is randomly selected to either accelerate by one growth stage of to develop a new bud. If the randomly-selected side is obstructed, then growth fails and nothing happens.
4. Each budding amethyst requires 4 growth stages to reach maximum maturity and be gatherable.

As such, the math can be applied if a player is within random tick range as to calculate amethyst growth rate:

(68.27 seconds/1 random tick) × (5 random ticks/1 growth stage) × (4 growth stages/1 amethyst cluster) × (6 amethyst clusters/1 budding amethyst block) = 68.27×5×6×4 = 8192.4 seconds for an unobstructed budding amethyst block to fully grow each of its clusters. This time is equivalent to 2 hours 16 minutes 32.4 seconds or 6.827 in-game days.

Decoration

They can also be placed on certain other types of blocks for decoration. The block must be solid and have at least one side that form a full surface: for example, they can be placed on the bottom of stairs (or top of upside down stairs), but not on their side, or top. They can also be placed on the bottom of bottom slabs and on the top of top slabs. Of blocks that meet these criteria, some are still excluded.

Amethyst clusters cannot be placed on:

• All non-solid blocks;
• blocks without any full surfaces, like fences, fence gates, walls, glass panes, iron bars, lightning rods, chains, heads, grindstones, bells, lanterns, cauldrons, anvils, conduits, decorated pots, chests, pointed dripstone;
• leaves;
• big dripleaf;
• honey blocks;
• chorus flowers.

Light

Small, medium, and large amethyst buds give off a light level of 1, 2 and 4 respectively, while amethyst clusters give off a light level of 5.

Sound

Uniquely among other blocks, an amethyst cluster in all its growth stages makes a quiet overlay sound when generally interacted with as well as its block breaking sound when hit with a projectile.

			20w46a				Amethyst buds can now be obtained with Silk Touch.[1]
			21w11a				Breaking amethyst clusters by hand, with a piston, or by other means now drops 2 amethyst shards instead of the 4 that it does when broken with a pickaxe.
							Previously, only an iron pickaxe or higher could cause 4 amethyst shards to drop, and other means dropped nothing.
			21w17a				Removed unused 'lit' blockstate.
?							The item models for some smaller amethyst buds have been changed so they appear higher in inventory slots.
