Game rules: Gems max at 10,000, the rest will be in the Mailbox and Mission Claim. Gems in the email must be claimed before they expire (there is a time limit). Gems from missions have no time limit. It is recommended to claim mission gems only after you have used up your current gems. Do not claim them immediately, as claimed gems will go directly to your email and have a time limit.
