Mineral Information – Quartz (Rock Crystal)

Quartz is composed of silicon dioxide (SiO₂) and crystallises in the trigonal crystal system. Rock Crystal refers specifically to the clear, colourless form of Quartz, valued for its glass-like transparency and well-defined crystal structure.

Quartz crystals typically grow as six-sided prisms with natural pyramidal terminations. Many specimens display crisp edges, reflective faces, and internal growth features that formed during slow crystallisation. Depending on the natural environment, quartz may contain faint internal veils, subtle inclusions, or wispy patterns that highlight its authenticity and geological history.

With a Mohs hardness of 7, quartz is a durable mineral that maintains its beauty over time, making it ideal for display, collecting, and educational study.

Geological Origin – Brazilian Quartz Deposits

Brazil is internationally recognised as one of the world’s most important sources of high-quality quartz crystals. Brazilian Rock Crystal commonly forms in hydrothermal veins and pegmatite environments, where silica-rich fluids cooled slowly within cavities in the host rock.

This slow natural process allows quartz crystals to develop excellent clarity, strong lustre, and well-formed terminations. Brazilian specimens are especially prized by collectors for their classic appearance and reliable quality.

Quartz deposits in Brazil are often associated with other minerals such as feldspar, mica, and tourmaline, reflecting the rich geological diversity of the region.

Display and Collecting Appeal

Rock Crystal Quartz is a timeless addition to any mineral collection. Its clear, light-catching surfaces make it visually striking in both traditional mineral cabinets and modern decorative displays.

This specimen’s natural transparency and crystal form make it suitable for:

• Mineral and crystal collectors

• Geology and natural history enthusiasts

• Educational collections and teaching specimens

• Unique gifts for collectors or nature lovers
