Blue Planet (ブループラネット, Burū Puranetto) is a card found in the Greed Island game. It is one of the game's 100 designated slot cards and so is required for a player to complete the game.
Blue Planet ブループラネット - This card allows the caster to summon forth an incredibly rare jewel known as Blue Planet. The jewel itself doesn't possess any particular ability like other jewels found in the game, but it does however give off beautiful blue shine. Its composition does not correspond to any known mineral on earth. As such, it was given this name to represent the saying "a gift from space".

A jewel shining in a true blue. The structural composition is not of anything found on the earth, so the name was given as "A Gift from the Universe".
- This is Bisky's favorite card in Greed Island. As such, this is one of the 3 designated slot cards Gon takes out of the game.
- Although generic, this card/jewel's name could be an allusion to the Earth that has been referred to as the "Blue Planet" already for some time due to the abundant water on its surface and/or the atmospheric hue.
