Amethyst expansion

Whilst exploring the nether there are many biomes but I am specifically referring to the warped forrest, and soul sand valley. In the warped forrest. there are items and mobs specific to that biome, the same goes for the chrimsion Forrest and sould sand valley. There are different torch and campfire colors as well as lanterns. There are many thins that set here part but I want to touch on the amethyst geodes. What if there were a block that turned campfires and torches purple or made to have an amethyst flame complete with amethyst sounds, sparkles, and textures. There could be a whole jewl cavern with rubies, emeralds, diamonds, jade, and even opal. These biomes could have block, mob, and even water specific changes. Axolotls in the water could have a different skin like how the villagers have different skins for different biomes. There are so many possibilities I cannot even fathom how big and beautiful these jewel biomes could sound and look.
