Clear rock crystal point with many rainbows

A clear rock crystal point from Brazil with numerous rainbow inclusions. The quartz matrix is of high clarity; spectral reflections move across the crystal surface in direct light.

Rainbow inclusions form on internal cleavage planes where light is refracted into its spectral components. They are not foreign minerals but rather diffraction effects within the crystal structure itself.

Brazilian rock crystal deposits yield this material in premium clarity. The combination of high clarity and a pronounced number of rainbow facets is a premium gemmological detail.

A well-balanced collector's size for the display cabinet. When illuminated from the side, the rainbow reflections light up along the growth axis.
