According to Aioly's Virtual Items Policy, all virtual items including gems are automatically forfeited if your account is terminated or closed. This means that any unwithdawn gems will be lost permanently. Before closing your account, it's important to withdraw all available gems through the withdrawal system. Once an account is closed, it cannot be reactivated, and there are no refunds or transfers for forfeited gems. If you're considering closing your account, make sure to complete any pending withdrawals first, as the process cannot be reversed after account closure.
