With screenshots, location of all 7 gems (6 large and 1 small). Version 0.1.216
 

1st Gem

 
The first one can be found in the basement of a home near the mines entrance. The gem is just a matter of climbing down the rope.
 
 
 

2nd Gem

 
After you disable the electric gate, you can find this gem close to a corpse.
 
 
 

3rd Gem

 
The next one is at the bottom of the pond with 2 coins in this cool lighting room.
 
 
 

Fourth Gem

 
The final section of the mines is located near the elevator. This is actually on the opposite side of the phonograph rooms. Neat.
 
 
 

5th Gem

 
This one is located in the same section as the elevator.
 
 
 

6th Gem

 
After exiting the mines, the final (and) small gem will be displayed in all its glory at a phonograph. Grab it now and get ready for the ultimate challenge…
 
 
 

7th Gem

 
Yep. The same place as the previous gem, but a little higher. Stacking props like this is the only way to get it currently.
 
 

 
I recommend saving after every successful barrel placement. The tower can can sometimes get a little wobbly.
 
IMPORTANT! If you enter a new level, the large gemstone will disappear from your inventory. If you wish to keep it, leave it at the lighthouse.
