Describe your suggestion:
There are forge tags allowing blocks to be used as beacon base blocks and that would be pretty cool, like an amethyst beacon. I suggest you add these tags to the storage blocks for the rare gems.

Describe alternatives you've considered:
Not really any since this is pretty straightforward.

Additional context:
Since these ores are fairly rare (on par with diamond) it would make sense. Also maybe let the amethyst be able to be used as a beacon payment item.
