I'm with you Tator_Tot - it's doesn't make sense economically. I've got no problem with paying for something, but at least make it reasonable. Bring the gem price down and make it so you can only buy 1. And 60 gems for 60 minutes? This is even worse. Again, not very economical.
As for the "Move Building" feature - no gems I hope. I'm willing to pay in resources, but not gems. I'll tear down a building before I pay in gems! Make it Hardwood or Marble or both, heck, even coins - but not gems. Make it take an hour to make a move or even 2 hours to make a move - but not gems!
