I’m working on a game right now, I’ll give some info:
It’s a team elimination game, like Super Doomspire, except the spawns are a center nexus.
The Nexus is a crystal pod, which you break to deactivate the team’s spawn.
Ok, here’s the icon!
I really like the design, and the unique shape it had!
The only thing I noticed, is that the emblem/crystal in the center, doesn’t really pop. This might be intensional, if this is a background icon, but if it isn’t I would up the brightness of the middle purple design.
If it’s meant to be an important crystal, it could also use a little bit of glow to make it seem powerful and significant.
Overall it looks very clean though!
Thanks for the feedback! I thought it looked dull after making it, but never really got to it 
The crystal IS powerful in a way, so I think it actually would be a nice touch.
Good job is cool. You created good icon👌
Maybe some reflection in the glass, like this:
And making the gem brighter would make it a lot better. 
Adding more detail, like text, lights. Will make it better! But good job.
