Max Gem Mine cost 1,500 Gems.
You get 15 Gems per day.
In 100 days, You will regain the 1,500 Gems you spent
The question is do you plan on playing the game for that long?
If the answer is Yes, You should get the Gem Mine.
It will pay for itself + gives you further profit moving forward beyond 100 days.
If the answer is No, You should blow the Gems on Shard Packs, Energy, or Masteries.
It will help you stay involved/hyped in the game till you quit the game.
