Bornite Specimen

Iridescent Bornite Specimen | Magenta, Copper & Gold | 345 g

Turn this bornite toward the light and its rugged face flashes magenta, violet, copper, and brassy gold. The strongest pinks and purples sweep across the upper face, while warmer bronze and gold tones gather along the lower ridges. Small hints of blue peek through the darker areas as you turn the specimen.

Jagged ledges and deep crevices catch bright highlights on their edges and hold shadows in the recesses. The rough, charcoal-gray upper surface frames the more colorful face. In softer light, the darker metallic tones come forward. In direct light, the ridges and broken faces light up in patches of color.

At 9 cm long and 345 g, it has enough heft to stand out on a display shelf and is easy to pick up and explore from different angles.
