Amethyst Cluster

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

Amethyst clusters are the 4th and final growth 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. Amethyst buds do not grow when placed on blocks other than budding amethyst.
