Description
A striking, complex hopper crystal of bismuth, characterized by its stepped, geometric growth and a vibrant iridescent surface displaying a rainbow of colors due to a thin oxidation layer.
Geological Context
This specimen is a synthetic crystal, grown under controlled laboratory conditions. Naturally occurring bismuth is found as a native element in hydrothermal veins and pegmatites, often associated with other metallic minerals.
