1. Leveling up is a good way to earn a decent chunk of Gems. Probably the fastest way, in the short term.

2. Investing in the Driller.

3. Try your luck with the Lucky Chest.

4. Find all the hidden Gems in the Campaign.

5. Watch an ad by presiding “Free Currency”.

There are more ways to pick up Gems, but I find these the most reliable methods, personally.
