The safest way to get gems in Clash of Clans is to earn them inside the game itself. Gems are the game's premium currency, and while you can buy them with real money, you can also collect a steady stream of free gems by clearing obstacles, completing achievements, running the Gem Mine, and grabbing seasonal rewards. This guide walks through every legitimate method, step by step.
Before we start, one important rule: gems only ever come from inside the official Clash of Clans app. Any site promising a "free gem generator" is a scam. With that out of the way, here is everything you need.
What you need
- An active Clash of Clans account on iOS, Android, or an emulator.
- A Builder Hall of level 3 or higher to unlock the Gem Mine.
- A little patience — most free gems trickle in over time as you play.
How to get gems in Clash of Clans
-
Step 1: Understand what gems are for
Gems are the most valuable currency in Clash of Clans. You can use them to instantly finish building upgrades, buy and activate extra Builders, boost resource collectors and barracks, and refill your shield. Because they are precious, it pays to spend them on long-term value — like a fifth Builder — rather than rushing every short timer.
Gems speed up upgrades and unlock extra Builders, so save them for high-value purchases. -
Step 2: Clear obstacles for free gems
Trees, bushes, rocks, mushrooms, and log jams spawn randomly across your village over time. Tap any obstacle and choose Remove to clear it and pocket a small handful of gems. You'll also occasionally find a rare Gem Box, worth 25 gems, plus special seasonal obstacles that can give even more. This is the simplest, most reliable free source in the game.
Clearing trees, rocks, and the occasional Gem Box drops free gems straight into your balance. -
Step 3: Complete achievements
The Achievements menu is the biggest single batch of free gems for newer players. Each achievement — such as Bigger Coffers, Sweet Victory!, or Heroic Heist — has three tiers that reward gems as you reach them. Open the achievements list and tap the green claim button whenever a tier is complete. Many achievements pay out as you play normally, so check back often.
Each achievement has three tiers — claim the gems as soon as you unlock them. -
Step 4: Build and collect the Gem Mine
Over in the Builder Base (unlocked after Builder Hall 3), you can construct a Gem Mine. This special building slowly produces gems on its own, with no effort required beyond collecting them. Visit your Builder Base regularly and tap the mine to scoop up what it has stored. Upgrading the Gem Mine increases how many gems it produces per day.
The Gem Mine quietly produces free gems over time — collect them every time you log in. -
Step 5: Buy gems in the Shop (and dodge scams)
If you want gems faster, open the in-game Shop, pick a gem pack, and pay securely through the App Store or Google Play. Bigger packs give more gems per dollar. Buying is completely optional, though — the free methods above keep gems coming in. Never enter your account details on any outside "free gems" website; those are scams that can steal your account.
Buy gems safely inside the app — and ignore any site promising free gem generators.
Tips for earning more gems
- Leave a spot open for obstacles. Obstacles only spawn on empty tiles, so keep some clear space inside your walls to maximize how many appear.
- Save for the fifth Builder. Spending around 2,000 gems on an extra Builder roughly doubles your upgrade speed and pays for itself over time.
- Don't waste gems on short timers. Skipping a few-minute build is a poor use of a rare currency — save them for big purchases instead.
- Watch for events. Seasonal challenges and special obstacles occasionally hand out bonus gems for free.
Troubleshooting
I can't find any obstacles to clear
Obstacles spawn on a timer and only on empty tiles. If your village is packed with buildings, clear a little open space and check back later — new trees and rocks will appear over the following hours and days.
The Gem Mine option isn't showing up
The Gem Mine lives in the Builder Base, which unlocks once you reach Builder Hall 3. Make sure you've travelled to the Builder Base (the boat on the coast of your main village) and have upgraded the Builder Hall far enough.
A website is offering me free gems — is it real?
No. There are no working gem generators or codes. Those sites exist to steal your account login or push malware. Gems are only ever produced inside the official Clash of Clans app.
Frequently asked questions
How do you get free gems in Clash of Clans?
Clear obstacles like trees and Gem Boxes, complete achievement tiers, and collect from the Gem Mine in your Builder Base. These are the main free, in-game sources.
How many gems does a Gem Box give?
A Gem Box obstacle gives 25 gems when removed. It's a rare spawn, so grab it whenever you spot one on your village.
What is the best thing to spend gems on?
Most experienced players agree the best long-term purchase is an extra Builder, since it permanently speeds up your upgrades. After that, boosting collectors and barracks offers good value.
Are free gem generators safe?
No. Every "free gem generator" is a scam designed to steal your account or money. Gems can only be earned or purchased inside the official app.
Do gems expire in Clash of Clans?
No. Gems are tied to your account and never expire, so you can save them up for a big purchase whenever you're ready.
Final thoughts
Getting gems in Clash of Clans comes down to a mix of patience and good habits: clear obstacles as they appear, claim every achievement tier, collect your Gem Mine, and buy a pack only if you genuinely want to. Stick to these in-game sources and you'll build a healthy gem balance without spending a cent — and without ever risking your account. For official details, see the Clash of Clans website.
