Yellow Diamond Flare Signal

Joy Ride 142

The Yellow Diamond Flare Signal is a flare signal that emitted from Peridot's Escape Pod in "Joy Ride".

The Yellow Diamond Flare Signal displays a complex web of geometric shapes overlapping each other into the sky when fired. The signal is composed entirely of straight lines of yellow light. Diamonds, squares, rectangles, and other various polygons can be seen within the signal.

It is unknown whether or not other Gem ships from Homeworld, such as the Gem Warship, possess the ability to emit the Yellow Diamond Flare Signal.

SU Gem satellite

The Gem Satellite is a mobile headquarters for Gem scouts collecting core samples on potential colony planets in "Steven Universe: Anti-Gravity".

The Gem Satellite appears in the Moon Base where it is suffering from a malfunction. Pearl then finds that the computer regulating the satellite’s operations is running tons of applications leading her to shut them all down. While Amethyst and Steven check out other areas of the satellite to make sure nothing else is wrong, an alarm goes off in the satellite and they find that a phaser is charging to shoot at Earth. Ronaldo, using his radio telescope, communicates with the Crystal Gems, and he miraculously makes a couple of suggestions that inspire them to turn the systems off, deactivating the satellite.

Steven Universe Volatile Gems

The Volatile Gems appear in "Issue 15" they are two temperature-sensitive Gems that can’t be bubbled like normal until they’re outside their protective temple, they are stated by Garnet to be like the Shooting Star, one Gem has to stay frozen and one Gem has to stay heated.

Steven observes while Sapphire claims the “frozen fragment” and Ruby claims the “scorching shard,” both Gems using their ice and fire powers to keep the volatile Gemstones at the correct temperature, unfortunaly Ruby and Sapphire struggle to keep their minds on their mission because they’re so distracted by their attraction to each other that they lose their focus and fail to keep the temperature on their captured Gems consistent, which whisks the Gems back to the hands of the temple’s statue this triggers a trap that shoots fire jets out of the floor and almost fries Steven. Garnet re-emerges and helps him retreat. The second time they try they cause the trap to shoot ice shoots out of the floor and almost stabs them, but Steven’s able to save them with his bubble. Steven leads the way back up to the statue where the elusive Gems are kept. He directs Ruby and Sapphire’s actions and has the bright idea of keeping them physically apart while they exit the temple, they make it out of the temple and Ruby and Sapphire are able to bubble their respective Gems.
