How to get Gems
Hungry Shark Evolution Guide
Gems are used mainly to continue a game when your shark would otherwise die. You can also use them to unlock higher-level sharks without having to wait to earn the Coins.
The best way to earn Gems is to watch out for 'Gem fish'. These glow green and you will see them around as you swim in the ocean - eat them and you will earn some Gems for your shark. You only get one at a time, but this method is much better than the alternative, which is to purchase Gems with your own money!
