So, as I have noticed, most singular gems have well known gemstones (ex. Ruby, Pearl, Sapphire, etc). Sardonyx is not a very popular gemstone, so my theory is that Sardonyx is a very strong fusion of the gems Sard and Onyx, who are being forced to stay fused (not like the cluster, but like they are always being watched by Homeworld so that they do not unfuse) in order to fight alongside the Homeworld Gems. Maybe, in Week of Sardonyx, Steven and the crystal gems will help Sardonyx unfuse and escape the clutches of Homeworld.
