Gems were often a problem for me too before I upgraded my castle to 13 and built the 2 extra mines during the anniversary sale a couple of months ago. Plus upgraded 1 mine to 12 for the quests. They boosts they had that month for the mines and lower gems to upgrade LRs helped a lot too and was what allowed me to finally catch up on making GLRs.

You can try looking for comrades to exchange gem mine taps since you'll get a bonus when comrades help. Make sure to do the daily quests that give gems too, especially the ones during tower. And if you haven't read it before, you can check out Choocolatiah's blog entry on minimizing gem expenditures for some ideas on how to cut down on gem costs.
