Gem

In Shadow Fight 2, Gems are the secondary currency which are accepted as a mode of exchange throughout the game. They can be used for every item for which the Gold coins can used. Addition to that, Gems can buy special item in the game which are not available to be purchased using Gold. This is especially true of those items which are readily enchanted by the game. But Gems are secondary in the sense that they are more difficult to obtain than gold coins and they can easily get exhausted because the amount won/bought is quite limited. It is thus advised that Gems should be used only for buying items that are otherwise unpurchasable using Gold, particularly those with enchantments.

Obtaining Gems
They can be obtained by these methods:
 * Boss defeats: They award you 3 gems.
 * Achievements: Most achievements when they are completed will award the player one gem each. Eclipse achievements will award 3 gems.
 * Tapjoy offers: Completing a task offered by Tapjoy will offer certain amount of gems to the player determined by the task. Players can access this through the "get free gems" option from the gems section of the shop. This method may not really offer gems after the completion of the task.
 * Watching Ads: The game rewards 1 gem for watching of each ad that can be viewed in the same section of the Tapjoy offers. However the ads are not always available but are sure way of earning gems.
 * Purchasing online: Gems can be purchased online for certain prices determined by the game.
