6,000 Gems for the Aires Network Refinery (5,000 + 1,000 bonus, +20%).

Spend them in game with /gemshop: ranks, keys, pickaxe skins, cosmetics and more.

You must be online to receive them: your Gems arrive while you're on the Refinery Spawn (type /spawn), usually within a few minutes. Bought while offline? They arrive the next time you join Spawn.
