I am the first person to put a tip on here , the easiest zone on Abberation has these and they are mineable, watch out for ravages though!

Also have a good day 😁

How do I get these on lost island?

One of the two places to find Green Gems on Fjordur, is the Hidden Grotto cave (36 LAT, 37 LON). It’s a normal cave that can only be accessed by swimming through a secret underwater area. It’s very deadly though, A LOT of Aberrant Megalosaurus and Aberrant Megalanias. The underwater entrance itself is guarded by loads of Megalodons. -KD

In aberration they fall from the ceiling during earthquakes, and are easy to find all around the portal area. They have a glow to them so they should be easy to spot. Watch out for basilisks, they spawn near the portal area (and ARK said that was the easiest spawn point 😤😤😤)

Have a good day peoples. 😊

Oooooo shiny. Get eaten by ravager*

Get loads on Crystal Isles, that’s the red blue and green, hope this helps.

You can sometimes find these in drops on genesis 2.

There seems to be no blue gem option so I'm putting this here. There are trees with white leaves in the wasteland that give blue crystallized sap, which is a replacement for blue gems. I don't know the most effective harvest method, but the wyvern's wing attack seems to do good.

This is a helpful tip, if you got some green gems (which are pretty heavy) have a ravager with you and put it in the ravager cuz they have weight reduction, for some reason don't question it

On Valguero there is a lot in the emerald forest :)
