multi-tips Black Brazilian quartz
PUMI2593-3
This black quartz multi-point cluster, weighing 960g, 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. This phenomenon, observed in various regions around the world, is particularly prominent in Brazil.
