In Clash of Clans, gems are a special currency that can be used to purchase nearly anything a player could want in the game: faster unit production, instant building completion, and even more resources. However, players only receive a small number of gems each week (earned by clearing plants and gem boxes from their base. If players want more gems, then they must pay real money.
Given that gems are not unlimited nor free, players need to take care to spend them in the most efficient way possible. This guide will focus on that exact topic.

The #1 Use for Gems: Builder’s Huts
Without a doubt, the best use for your first few thousand gems will be Builder’s Huts. Each Builder’s Hut provides the player with one additional “Builder”, which can then be used to build and upgrade structures for the player’s base. Each structure under construction or being upgraded requires a builder. The more Builder’s Huts you have, the more buildings you can upgrade or build at the same time. Each additional builder significantly improves your upgrade speed.
Builder’s Huts can only be bought with gems. There is a limit of 5 total huts, and each hut becomes more expensive than the previous hut. Here are the costs:
Builder Hut #1: No Cost
Builder Hut #2: 250 Gems
Builder Hut #3: 500 Gems
Builder Hut #4: 1000 Gems
Builder Hut #5: 2000 Gems
If you want to buy gems to speed along your upgrades, be sure you are using them on Builder’s Huts. If you do not want to spend money, rest assured – you can eventually unlock all 5 builder slots by completing achievements and saving gems from debris clearing.
Best Use for Gems After Builder’s Huts
Even if you never buy gems, eventually you will be able to collect the 3,250 additional gems required to unlock all 5 Builder’s Huts (each new account starts with 500 free gems). Whether you buy gems at this point or begin to acquire them for free by clearing debris, gem boxes, and unlocking new achievements, it is important to understand how to best spend these gems to advance your base.
All gem-spending activities are not created equal. Some are clearly much better than others. I believe the most efficient means for increasing speeding along base upgrades results in boosting the Barracks. Boosting each Barracks only costs 10 gems and lasts for 2 hours. This effect causes the Barracks to produce units at 4 times the normal speed. If you boost 2-4 Barracks (depending on army composition), you can practically raid non-stop for 2 hours, netting 2x-4x the loot you normally would from farming for that length of time without the boost.
