If gem drills were there when the game started, Supercell would've lost many millions of dollars.

Even if there was a gem drill, it should have 3 levels. Level 1: Build time-2d Build Cost-3141592 gold 1 gem per week

Level 2: Build time-13d Build Cost-3141592 elixir 1 gem per 4 days

Level 3: Build time-61d Build Cost-200000 dark elixir 1 gem per day.
