If you want to obtain a whole cluster, you need to use a tool with the silk touch enchantment. If you employ another extraction method, then only 2 shards are dropped.

If you destroy an amethyst cluster with a pickaxe, you can get 4 shards. When it is destroyed, amethyst shards are dropped. It is the last stage of an amethyst bud’s growth. To get a bud, you will need a tool with the silk touch enchantment. Each stage is a separate block - this is the salient feature of this block as a growing one. First, a small bud appears, later an average one sprouts, and then a large one can be seen. It is used only in a cave itself when clusters germinate on it. Even if you use a tool with the silk touch enchantment, you still won’t get it. If you break such a block, nothing drops out of it. It is another block generated in amethyst geodes. It can also be obtained in another way - by connecting 4 amethyst shards. In this update, the amethyst block is not used in crafting - perhaps it will become very useful in the future.

Unlike the budding amethyst, it is very easy to get - it will be enough just to dig with a pickaxe. It is a block generated in the new caves - amethyst geodes - right inside them. They are not so rare, so it’s quite easy to find them. It consists of amethyst blocks and their varieties. Most often generated at the height from 0 to 40 but can also appear at a height of up to 60. It is a new biome, or rather a structure that can be seen deep underground. It is the first Caves & Cliffs update, in which many new blocks, objects, and creatures appeared. The 1.17 version is a global update for Bedrock Edition, released on June 8, 2021.
