Here is the Discord.
And yes, hunting creatures is currently the most effective way to get gems, and also taking part and looting meteors.
As far as gleam, if you’re looking for red gleam you’re out of luck that’s really hard to get. Yellow, and blue is found in graves scattered around. Under the small graves made of rocks. Planet Munteen gives you blue, planet Nasharil gives yellow. If you travel to elope portas you can easily find cream gleam.
A guild call Portal Seekers run hunts daily, you can either tag along or join them and you’ll have mates to watch your back!
I would join, but I work a lot…
