▶Produced byThe Crystal Block is a rare block, only obtainable through a Special Event, where players have thirty seconds to find a Crystal Block seed before it disappears. It can be spliced with other seeds such as the Golden Block seed to make Diamond Ring or can be planted to make the Crystal Block itself.
- Very early on, when the Crystal Block was introduced, it was accidentally made obtainable through the Rare Seed Pack. It was later removed, making the item extremely rare. Since the item was completely unobtainable, it was made available through the Special Event on the 13th of March, 2013.
- On the 18th of March 2013, a server update made a tweak on the texture of the Crystal Block to make it slightly more different to the Glass Block. The design was credited to former moderator meow who posted a suggestion of the current graphic on the forums.
