Rock Crystal Pyramid

A polished rock crystal pyramid from Brazil with a clear internal structure, fine inclusions, and rainbow reflections when light passes through.

Rock crystal (SiO₂, Mohs 7) is a robust quartz with high light transmittance. The pyramid shape supports the refraction of incident light into individual spectral colors.

Such rainbow inclusions form on microscopic fracture surfaces within the crystal, where interference colors become visible. They are a quality characteristic of clear Brazilian material.

The pyramid is cut all around and polished to a high gloss. It is suitable as an accent on a desk, console, or in a meditation room.
