Quartz Mineralogy

Quartz is a naturally occurring mineral composed of silicon dioxide, with the chemical formula SiO₂. It is classified within the silicate minerals and is recognised for its crystalline structure, durability and broad geological distribution. Rock crystal is the clear or colourless form of quartz. As with natural mineral specimens generally, the visual character of an individual piece is determined by its own growth history and the conditions in which it formed.

Quartz crystals commonly develop a hexagonal crystal system and may show a prismatic habit with pointed terminations. Natural crystal surfaces can include growth features, planes, edges and other characteristics produced during formation. Quartz has a Mohs hardness of 7, making it a durable and well-known mineral for display and collecting, although individual specimens should still be handled with care to preserve their natural surfaces.

Geological Context

Quartz forms in a wide range of geological environments, including mineral-rich fluids moving through cracks and cavities in rock. As these fluids cool or change chemically, silica may crystallise and produce quartz growth. Brazil is internationally recognised for its important quartz-producing regions and long-standing connection with mineral collecting. This specimen is identified as Brazil material, while its supplied product information does not specify a more detailed locality or formation.

Collecting and Display

This specimen is suited to a home mineral collection, classroom geology display, crystal cabinet, office shelf or curated decorative setting. It can be displayed individually as a focused example of quartz or arranged with other mineral specimens to illustrate differences in crystal form, colour and geological origin. Its association with the Alice Purnell Collection also gives it added interest for collectors who value documented collection pieces.
