Gems are the sole currency in Growtopia. They can be obtained through in-app purchases, completing Tapjoy offers or through common aspects of gameplay, such as breaking blocks and harvesting trees.
Gems group together when there is a certain amount of gems in the tile. As the value of the gem increases, the size of the gem also increases slightly (the table below, however, does not show the size difference).
Earning 3500 gems or more through Tapjoy offers or in-app purchases grants the player the Supporter rank. If you buy $25 worth of gems, you will get super supporter status with 4 new skin colors and the /warp command since the Systems Update came out, on September 2nd, 2017.
Gem Drops
Each type of block or tree in Growtopia drops a different amount of gems. This amount is usually influenced by the rarity of the block or item, but some blocks drop an unusually large amount of gems as they have been configured to. A good example of this is the Mystery Block. When one is broken, the amount of gems it yields can range from 10 to 50. Another example of this is the Pot O' Gold, an extremely rare block that is only available during St. Patrick's Week, which can yield up to 200 gems when broken.
Methods of Obtaining Gems
There are many ways of obtaining gems in the game.
Farming
Farming is the process of harvesting a set amount of trees of a specific item, breaking the blocks and planting the seeds. The process is then repeated.
In-App Purchases
In-app purchases, or IAP, allows players to buy different amounts of gems with the use of money. This is the only legal purchase in the game which involves real money. Purchasing the Gem Fountain will give you an extra Growtoken, and purchasing the It'sRainin' Gems also gives the buyer 2 Growtokens and a Megaphone. During some events such as the St. Patrick's Week or Anniversary Week events, some bonuses may be given when purchasing gems through IAP.
Dialing the number "12345" using a Telephone will connect you to Crazy Jim, who offers three daily Life Goals. The second Life Goal in the list is the Gem Goal. When completed, the Gem Goal will reward you a random amount of gems depending on your Awesomeness, with 0% awesomeness giving the least gems and 100% the most gems. Once completed, the Gem Goal will not be available again until 0:00 of the next day (UTC-0500).
Tweaks
Patches and tweaks have been made to balance the game and to prevent scams.
