If you’re on abb I would recommend going into the Red zone and mining some. But if on genesis just go to the ocean biome and go to one of the underwater tek cubes and one of them has all 3 crystal types in it hope this helped.

Abb radiation zone on Valguero I think gives the most per crystal. You get red and blue gems

The bubbles in crystal isles has alot of them

You need these for drake saddles

Just use a doedicurus, it gets so much red gems

You can use a dodicirus or ankylo I play on lost island and i play with primal fear so if you do to then i recommend that u put the dino ur farming gems with on wandering then u pick it up with an argy and then let the dino farm the gems then when u have enough gems go back home then turn wandering off that's how I harvest gems

how to get: go to abb or a abb cave such as fjordurs abb cave, then mine it. note: green gems i think cant be harvested from a pick, also wanting this on a map that doesn’t have this such as the island? just use the obelisk terminal and put it in the items tab you can also put creatures in the creature tab. they just need to be on the terminal platform. note: it will remove saddle and inv. so maybe use cryos to at least keep saddle. you cant put cryos in the creature tab though. then go to a obelisk on that map and grab them. note on servers there is a timer about how long they can be in there. so its not just a every map chest. punch the sky if helpful

Like a normal gem… but red
