Neal Luppescu Talk for the Tucson Gem & Fine Mineral Show 2025

The Tsumeb deposit is celebrated by collectors for its exceptionally diverse range of mineral species, many of which form stunning, collector-quality specimens.

A single specimen may showcase multiple species, whether through the formation of a pseudomorph, a cast, a phantom, or a coating.

These processes highlight the complex chemical and crystallographic transformations underlying the creation of these remarkable pieces.

Neal Luppescu’s presentation will feature many aesthetic examples that illustrate the extraordinary diversity of specimens from the Tsumeb Mine.
