In the early days, the Gems were ridiculously rare, daily rewards would only reward 5 until two updates (one that changed to 15 and 25, and the current one), invite friends would reward Coins and even members would only start to be rewarded 500 monthly up until v1.03, July 25th, 2013. Unlike Coins, only registered players start off with 75. They are represented as purple gems ( ), which just like Coins, the amount of Gems in the icon changes.
