Xeraphinite is named after seraphinite, which a variety of chlorite, a group of phyllosilicate minerals.
It typically has a shade of forest green, often with a strong chatoyancy effect.
This is often known as the "cat-eye effect", and for seraphinite, these resemble feathers of a seraph (plural: seraphim), hence its name.
According to a statement from BlackY, Xeraphinite is the sequel to Alexandrite.[2]
The chart design credit translates to "Toaster ※ Sapphire". This alias was first used for Alexandrite.
This song was available ahead of the official release via a serial code included in the physical version of the album Memories of Realms, along with its extended version.
