Natural Fluorite
Notland
Fluorite is calcium fluoride, soft and perfectly cleavable, and only rarely encountered as clean transparent rough in a saturated purple. The colour arises from trace chemistry and lattice defects rather than from any treatment.
Notland is a 525.23 ct purple cushion, cut in a combined brilliant and modified step pattern, and documented as natural fluorite with no detected treatments and no phenomena.
Rarity Score: 8.9 / 10

A matter of scale
At 525.23 ct and 49 mm across the table, Notland sits far above the size at which clean purple fluorite is normally faceted, holding an even colour across the whole face.
Fragility
At Mohs 4 with perfect octahedral cleavage, fluorite is among the most delicate faceted gems. Handled with gloves, never ultrasonically cleaned.
Provenance
Acquired as a single loose stone with laboratory documentation; chain of custody is recorded from the cutting workshop to the Institute.
Documentation
Verification is in progress. Laboratory documentation, photographic record and acquisition history are held on file and shared in full with serious enquirers.
