Yo anybody that needs to know how where they spawn on rag they spawn at 49 latitude and 32.5 long on this little snow top there's a few crystal gems there that will give you a few.

Mining drill Overpowered for blue gems, USE IT, or at least put it on 2 for this list.

54.3 71.0 on lost island look to find a massive cave with little entrance go past boat.

If you play on extinction break the trees with white leaves, they give blue crystilized sap which works like this. Becareful because corrupted creatures hurt. Would recommend going near the desert some because worst thing is corrupted rex

Where do you get it in genesis i don't know

Roll rats sometimes drop blue gems as well if you are on abberation. Only works if they are wild though.

Tip for first time getting these things:

There’s a little “staircase” down to the bioluminescent on abberation (it’s the only land entrance that doesn’t require a jump, iirc) which is a transition zone. There’s a fair amount of blue gems for the taking. Be prepared to fight off various creatures on the way and while there (rock drakes, too).

Any tips for ragnarok getting these?

And what about ragnorok where can I find blue gem
