“It sparkles with cold energy.”

The Blue Gem is an item used to craft several Magical Items. It can be used to craft the Ice Staff, Chilled Amulet, and Purple Gem.

Blue Gems can be used to turn Chester into Snow Chester by placing at least one in each of his inventory slots on a full moon. Snow Chester's special ability is preserving food longer like an Ice Box.
