Natural Fluorite
Nova
Colour-change fluorite is one of the quietest optical rarities in the mineral world: the same stone reads blue-green in daylight and violet under tungsten light, a shift driven by trace chemistry and lattice defects rather than by any treatment.
Nova is a 581.93 ct transparent cushion, documented as natural fluorite with a genuine daylight-to-incandescent colour change and no detected treatments.
Rarity Score: 9.3 / 10
