HELP!! AWAKENING GEM!!!

I have a 4* generic awakening gem. Should I save it for something like SW or BW, or do I use it on my maxed out 4* AA. I'm currently in Act5.1 and main focus is becoming Uncollected. I don't plan on doing the RoL or Labyrinth anytime soon...what should I do?? 
Thanks for the help..

Mhm... So should I wait until i get a SW or SL, or use it up on my AA...?? Which would be more useful in 5.2??
P. S---i do have about 70+ generic sig stones
