The Wailing Stone is an artifact found by the Crystal Gems in the episode "Rose's Room". It appears that the Wailing Stone can only send audio, but is capable of receiving both audio and video (although it is not originally intended to receive the latter). It was used in the Rebellion, as confirmed by Pearl, to send messages back and forth.
Wailing Stones appear to have two significant parts: the "button" on top and its hole, which the audio plays out of.
The Wailing Stone's abilities can be augmented so that it can interpret messages that are usually too advanced by integrating it into a television.
The Crystal Gems found the Wailing Stone on one of their missions in the Northern Hemisphere. When the stone is activated by pushing the button at the top, it emits a thunderous, ear-piercing sound that causes objects to break, such as Steven's television screen.
Lapis Lazuli uses advanced Gem technology to warn Steven of the Homeworld Gems' coming arrival to Earth on their hunt for him and the Crystal Gems. The Gems are unable to decipher the message until Greg converts it into video due to the Wailing Stone's abilities being limited to playing audio.
- Audio from a Wailing Stone cannot be muted, but it can be muffled (as seen in "The Message"). Attempting to turn it off failed, along with trying to bubble it.
- The sound effects for the Wailing Stone were made by Rebecca Sugar playing on a modified Omnichord, and Toy playing on effect pedals.
- It has been shown that Wailing Stones can magnify the voices of humans and Gems, as unexpectedly demonstrated by Steven in "The Message".
- The gold patterns on the Wailing Stone resemble typical designs for containing cabochons.
- There is a giant wailing stone located in The Great North.
