multi-tips Black Brazilian quartz
PUMI2593-4
This black quartz multi-point cluster, weighing 965g, comes from Brazil’s mineral deposits, known for their unique crystals with deep hues. This quartz, so dark it appears almost black, owes its color to a fascinating natural phenomenon: natural irradiation.
When aluminum impurities within the quartz are exposed to radioactive minerals such as uranium or thorium, often found in the surrounding granite, a gradual change in coloration occurs. The longer the exposure to radiation, the darker the quartz becomes.
A piece that captures both light and imagination.
