Warning: this pack contains flashing textures, flashing at a rate of 1 frame per second, if you are sensitive to flashing images it may be best to avoid this pack.
This pack changes all the ores, including amethyst, to act like neon signs using an animated emissive texture. This pack should be used with Optifine since while it will still animate without it it will not have the proper glowing effect.
This pack is designed for 1.19.2 however it works in 1.13 onwards. It does mostly work on 1.19.3 as well however nether gold ore will have the default texture.
