Three new gemstones with matching tool and armor sets: Peridot, Rose Quartz, and Ruby.
Three new biomes with new sand variants: The Purple Desert, the Pink Desert, and the Green Beach.
Green sand can be crafted into Peridot shards, pink sand into Rose Quartz shards, and purple sand into Amethyst shards.
Ruby and Peridot can be mined underground. Peridot generates lower down, being more likely to generate as deepslate ore, while Ruby generates in the middle range.
Also, fair warning: This is an MCreator mod, and I am not very experienced with modding, so this might have a few bugs.
