ON THE BENCH / 3D STUDY 02 · FLUORITE

Purple fluorite,
Weardale.

Frazer's Hush, Weardale, England.
Turn it over: the old collection label is on the underside.

Scan info 360°

Full 360°: the specimen was photographed upright and then flipped, and the two sessions were joined into one model by matching their outlines, because no photo shows both sides at once. The join is close but not exact, so detail is softer where the two halves meet, and fine crystal detail is softer than the photographs.
