Silver

Previously Pink Diamond's personal messenger... and miscellaneous helper Gem. Some time into the war, while on a errand at the Moon Base with Platinum, a Crystal Gem raid to drive Homeworld Gems away from the planet caused the two to hide a little too well, and the pair were left behind. With no way off the planetoid, they waited out the years here, hoping that somebody would come back. No help ever came, but Angel Aura Quartz was eventually formed, and he's been together ever since.

When unfused, Silver is surprisingly an anxious wreck. He's prone to overthinking and getting really sweaty for some reason, but Platinum always manages to sooth him. He's also very into collecting things like stationery and following a routine.
