Badge of Badges (Diamond) is for achieving 100 or more official World Anvil badges. (Not including the membership tier badge)
 

Badge of Badges

The Badge of Badges started as a little inside joke on the World Anvil discord server before the Catalysm™ incident. Created by Annie Stein, they were an unofficial silly way to display that you had many official badges. You can never have enough badges; this satisfies the need for a badge that acknowledges surpassing a specific number of official badges obtained.
  The Badge of Badges collection is a community-oriented badge and not an official World Anvil badge or award. There is no moderation on this, and it is based on the honor system, where you can add it to your profile according to the number of official World Anvil badges you have earned. The membership tier badge (Master, Grandmaster, Sage, etc.) is not typically included in the total number of badges counted towards this, as it is obtained through a paid subscription.
  There are several tiers of the Badge of Badges; the requirements for achieving them increase exponentially.
