Cyan Stained Glass is a dyed variant of glass that retains transparency while displaying a cyan tint. It is crafted by combining glass blocks with cyan dye. Like regular glass, Cyan Stained Glass must be broken with a Silk Touch-enchanted tool to drop itself; otherwise, it shatters. Mobs cannot spawn on it, and they perceive it as opaque, even though players can see through it.

Cyan Stained Glass can be used to modify the color of beacon beams by averaging its RGB color values with other stained glass blocks stacked above the beacon. Additionally, it serves as a crafting ingredient for Cyan Stained Glass panes.
