Geological Formation & Brazilian Locality

Brazil is one of the world’s most famous sources of high quality quartz crystals. Rock crystal forms over millions of years when silica-rich fluids circulate through fractures and cavities in host rock, slowly depositing layers of quartz.

This process creates the classic six-sided crystal structure with naturally pointed terminations. Brazilian quartz is especially renowned for producing:

• Bright clarity

• Well-formed crystal points

• Attractive natural growth surfaces

These specimens represent a remarkable piece of Earth’s mineral history, formed deep within the crust under specific temperature and pressure conditions.

Colour, Clarity & Natural Features

High grade rock crystal is appreciated for its clean, icy transparency and reflective surfaces. Individual pieces may show natural characteristics such as:

• Clear to slightly misty internal zones

• Subtle inclusions from natural growth

• Light surface texture or growth lines

• Occasional tiny mineral traces from formation

No two specimens are identical, making each one a unique natural collectible. These pieces are not dyed or artificially altered, preserving their authentic mineral appearance.
