amethyst crystal crafting

I think if we took a block of amethyst and put it on the crafting table, it could generate four amethyst crystals. as this would lessen the difficulty we have in making materials with amethysts, as in some geodes we only see growing amethysts. and that makes it difficult to get them. also, geodes are not so easy to find. and this frustration can be a complement, because when we find a geode, we don't get the desired amethyst crystals, because they are still in their growing phase. with this problem already fixed, we would no longer have frustrations with this requirement.
