Gems are the in-game currency required to make purchases from the Gem Store. The amount of gems you hold is indicated in the bottom left of the inventory panel and upper left of the Gem Store. Gems may be spent on convenience or cosmetic items, or account services.
Gems can be obtained in-game:
- By exchanging coin in the Currency Exchange tab of the Trading Post panel
- As an achievement reward of 400 every 5,000 achievement points
Gem cards can also be bought from local retailers or online in different denominations
Gems can be purchased for real-world money in several fixed amounts in-game. There is no discount for bulk purchases.

 Currency Exchange
The Currency Exchange tab allows you to trade gold for gems and vice versa. The exchange rate is measure in coin per 100 gems and determined by supply and demand from players. The average rate for exchange is displayed below along with the 5 day high and low. A graph displays the average price for the past week. There is a 15% transaction fee for converting in both directions. For example, exchanging 1 gives 85 worth of gems while reselling those gems returns only around 72 25 , a net loss of roughly 28%. As the average price is decided by player supply and demand, prices will often change rapidly when new items are added to the Gem Store or there is a demand for coin. Purchasing gems to convert to coin is a common practice for players. The maximum amount of gems that can be traded at one time is 9999. The maximum amount of gold that can be traded at one time is 200 .
