The Iridescent Gem is a Don't Starve Together exclusive item, introduced in A New Reign. It can only be acquired by using a Deconstruction Staff on the Moon Caller's Staff. Currently it has no known uses, as the Moon Caller's Staff cannot be crafted.
- The Iridescent Gem was introduced in the A Little Fixer Upper update.
- The gem bears a strong resemblance to an opal, having a white hue with a colorful tint. This is also indicated by the gem's spawn code.
- This gem is the only item that can only be obtained by destroying something with a Deconstruction Staff.
- Winona's quote ("Pretty! Pretty useless.") is a reference to the fact that the Iridescent Gem has no use.
