- "This mysterious mineral gives off a pale blue glow in the dark, which some believe to be the souls of the dead. Apparently, this stone can be used as a base to make special clothing."
- — In-game description
Luminous Stones are items in The Legend of Zelda: Breath of the Wild. They can be found in Luminous Stone Deposits throughout Hyrule. Luminous Stones are primarily used to purchase and upgrade the Radiant Mask, Shirt and Tights set at the Gerudo Secret Club in Gerudo Town. The "Radiant" armor set are crafted with Luminous Stones to create their glow markings in the dark. They are also used for the sidequest Luminous Stone Gathering. After the quest, Link can give ten Luminous Stones to Ledo in exchange for a Diamond. Link can sell them to shops for Rupees or use them as a dyeing material at the Kochi Dye Shop.
Luminous Stones glow at night, making it easier for Link to find their Ore Deposits, or in dark areas such as Thyphlo Ruins. Although the light produced is dimmer than fire or torch light, Link can use them to light up these dark areas. The stones were used to build Zora's Domain and can be seen in many of its sculptures and lampposts.
