The Iridescent Gem can be fed to Rock Lobsters, Slurtles and Snurtles , socketed into the Crab King (for the effects of one of each gem), or placed upon an Ornate Pedestal to power the Ancient Archive. It cannot be used to craft the Moon Caller's Staff.
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 is obtained exclusively by destroying something with a Deconstruction Staff, as well as being the only gem that is not destroyed by the Deconstruction Staff.
Unlike other Gems, the Iridescent Gem cannot be socketed into Cratered Moonrock or into Winona's G.E.M.erator. Trying to do so in either case will trigger a failure announcement:
“This gem won't work here.”
–Wilson, after failing to socket an Iridescent Gem
“It's the wrong rock!”
–Willow, after failing to socket an Iridescent Gem
“Little rock does not want to go there.”
–Wolfgang, after failing to socket an Iridescent Gem
