More gems in 1.17?

While a cave update is great, I would like to see more ores like ruby, citrine, pearl. I think new ores can serve as upgrade materials for enchantment and also beacon! Each crystals can be used for upgradiy the beacon like the diameter it affects, level of the effect, weaken mobs in the area such as adding strengh will give mobs weakness. There is little to no update to the beacon mechanism since 1.4. Also, they can be currencies of an underground economies. They can be biome-dependent like citrine only works and can be found in deserts, ruby in mesa, sapphire crystal in like dark oak forest, etc. Perhaps these crystals can be use for different kind of lens for the spyglass. Lastly, something could be activated or powered by collecting all gems(emerald, citrine, amethyst, sapphire, ruby) and combine them together. I don't know, perhaps ways to hatch the dragon egg or something.
