If and when the mod updates to 1.17, I propose in this post that the Amethyst of the mod should be replaced by Vanilla Amethyst. I suggest this mainly because Vanilla Amethyst in the Vanilla Snapshots have more uses than the mod Amethyst. Also, Amethyst Geodes should spawn within Middle Earth. Calcite and Smooth Basalt would still spawn around the Geodes. The thing that should be done is that the mod Amethyst trading use should apply to the Vanilla Amethyst.
