at lvl 6 you get a single gem every time the Clock Tower finishes cooldown. not counting the progress you get from Clock Tower itself. so from a lvl 6 Clock Tower you get 56 minutes to subtract that from the 7~ hour production time per gem and that is 6 1/2 hours and during that time while CT is on cooldown the GM will produce a gem on it's own. and that is not even counting any CT potions which add up 240 minutes (or 4 hours) per potion. and subtract that from the 6 1/2 hours (assuming you used the free boost prior) and it will take only 2 1/2 hours to make a gem.
