Cubes in green, purple and blue, and the mineral that named fluorescence.
The aesthetic
Fluorite is a calcium fluoride that grows in near-perfect cubes and octahedra, banded in green, purple, blue, yellow and colourless, often several colours layered within one crystal. It gave its name to fluorescence, glowing blue-violet under ultraviolet light. It is soft and cleaves perfectly in four directions, which is how octahedra are cut from cubes and why it chips if it is treated as tougher than it is.
The dynamic
Fluorite is described as a stone for order and concentration, associated with clearing mental clutter and with study, and is often called the stone for organising a scattered mind.
