'''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 shard]]s 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 shard]]s, 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 {{fraction|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 geode]]s, on exposed faces of budding amethysts.

{{block distribution}}

=== 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 into amethyst clusters ===
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 shard]]s when mined.

{{IN|Java}}, the below logic can be applied:

# 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.
# Each random tick assigned to the budding amethyst block has a 20% chance of creating a new amethyst bud or incrementing the growth stage on ''one'' randomly-selected side of the six-sided block. And if the randomly-selected side is obstructed, then it fails and nothing happens.
# There are 4 growth stages.

As such, the math can be applied if a player is within random tick range as:

(68.27 seconds average for random ticks) × (20% chance of growth for any given single side) × (6 sides) × (4 growth stages) = 68.27×5×6×4 = 8192.4 seconds average, also 2 hours 16 minutes 32.4 seconds, also 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 side sides 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 [[Solid block#List of non-solid blocks|non-solid blocks]];
* blocks without any full surfaces, like [[fence]]s, [[fence gate]]s, [[wall]]s, [[glass pane]]s, [[iron bars]], [[lightning rod]]s, [[chain]]s, [[head]]s, [[grindstone]]s, [[bell]]s, [[lantern]]s, [[cauldron]]s, [[anvil]]s, [[conduit]]s, [[decorated pot]]s, [[chest]]s, [[pointed dripstone]];
* [[leaves]];
* [[big dripleaf]];
* [[honey block]]s;
* [[chorus flower]]s.

=== 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.

* While amethyst buds cannot be equipped in the head slot in [[Survival]] mode, equipping it using [[commands]] causes it to appear as a crown.
