In the changelog, it said that amethyst buds can be silk touched at any stage. However, when an amethyst bud that hasn't grown into an amethyst cluster is silk touched, nothing is dropped.
Steps to recreate:
Go to an amethyst geode
Have a pickaxe with the silk touch enchantment
Mine an amethyst bud that is not fully grown with the pickaxe in survival mode
Watch it not drop anything

This is being tracked already in MC-203631. It is true that they should be obtainable with silk touch, since that was mentioned in the patch notes.
