The bug
Amethyst blocks are not grouped with any of the blocks one may expect them to be grouped with. They are not grouped with diamond or emerald, despite amethysts, diamonds and emeralds all traditionally being precious stones, nor are they grouped with quartz blocks, despite amethyst being a variety of quartz.
The recommend fix for this would be moving all four families of blocks next to each other.
How to reproduce
Open the Creative inventory
Locate Block of Amethyst in Building Blocks
Locate Block of Quartz in Building Blocks
Locate Block of Diamond in Building Blocks
Locate Block of Emerald in Building Blocks
Note that there is a considerable distance between these items

Relates to MC-1797.
To me it makes more sense to group it with quartz because Amethyst blocks cannot be converted back to amethyst, similar to quartz, meaning it is not a storage block and they have the same crafting recipe.
Can confirm
