Amethyst Cluster

Amethyst buds are 3 crystal block stages that grow from budding amethyst.

Amethyst clusters are the 4th and final stage of amethyst buds.

Breaking
Amethyst clusters must be mined with an iron pickaxe or higher, dropping 4 amethyst shards or more with Fortune, otherwise it drops nothing. When mined with Silk Touch, the amethyst cluster or amethyst bud drops itself instead.

Natural generation
Amethyst buds and clusters are naturally generated as part of amethyst geodes.

Usage
Amethyst buds have three growth stages – small, medium, and large – before becoming amethyst clusters.
