Mineralogy

Quartz is a silicon dioxide mineral (SiO₂) crystallizing in the trigonal crystal system, commonly forming prismatic crystals with well-developed terminations.
Siderite is an iron carbonate mineral (FeCO₃) typically forming rhombohedral or massive aggregates and is often associated with hydrothermal quartz.
The quartz–siderite association is a classic example of hydrothermal mineral formation.

Origin

Panasqueira, Portugal, is a world-famous locality known for producing high-quality quartz, siderite, fluorite, and sulfide mineral specimens.
Specimens from this locality are well documented and highly respected in the international mineral collecting community.

Why Collect

Quartz crystals with tourmaline inclusions are highly desirable among mineral collectors due to their combined mineralogy and aesthetic contrast.
Reasons to collect:
  • Natural quartz crystal with visible tourmaline inclusions
  • Well-known and classic African locality
  • Untreated, authentic mineral specimen
  • Suitable for cabinet and reference collections
This specimen represents a clear example of multi-mineral crystallization in natural geological conditions.
