The Celestial Stone is a Hardmode post-Golem accessory crafted from a Sun Stone and a Moon Stone at the Tinkerer's Workshop. It offers the same boosts as its components do, and as such, it is active during both day and night. It can be combined with the Moon Shell to form a Celestial Shell.
- The Celestial Stone does not show when equipped, despite the fact that its ingredients do.
- Of the accessories, the Ankh Shield and the Celestial Stone give the third most base defense, being bested by the Flesh Knuckles (7 base defense), the Celestial Shell (7 defense when worn at night), and the Paladin's Shield (6 base defense).
