Mineral Species Overview – What is Quartz?
Quartz is one of the most abundant and widely collected minerals on Earth, prized for its durability, crystal structure, and natural beauty.
Scientific classification:
-
Mineral Name: Quartz
-
Chemical Formula: SiO₂ (Silicon Dioxide)
-
Mineral Group: Silicates
-
Crystal System: Trigonal (Hexagonal family)
-
Hardness: 7 on the Mohs scale
-
Lustre: Vitreous (glassy)
-
Transparency: Transparent to translucent
-
Typical Colour: Colourless to milky white, sometimes with natural inclusions
Quartz is a foundational mineral in geology and is found in a wide variety of rock types and environments worldwide.
Geological Formation & Madagascar Locality
Madagascar is internationally renowned for producing exceptional mineral specimens, including quartz clusters, tourmalines, and other silicate minerals. Quartz groups from Madagascar commonly form in:
-
Hydrothermal veins
-
Pegmatite deposits
-
Metamorphic rock fractures
These environments allow mineral-rich fluids to circulate through rock cavities. Over long periods, silica crystallises into quartz, often producing well-developed crystal points and cluster formations.
Madagascar quartz may occur alongside minerals such as:
-
Feldspar
-
Tourmaline
-
Mica
-
Calcite
The island’s diverse geology and slow crystal growth conditions make it an important source of collector-grade quartz specimens.
Crystal Group Structure & Natural Features
A quartz crystal group consists of multiple intergrown crystal points that formed together in a natural cavity. Specimens may display:
-
Terminated crystal tips
-
Multiple points radiating from a shared base
-
Natural surface textures and growth lines
-
Clear to milky translucency
-
Occasional inclusions typical of natural quartz
Each cluster tells a geological story of slow mineral growth over millions of years, making quartz groups highly valued for both display and scientific interest.
No artificial enhancements are applied—these are completely natural mineral formations.
Large Size & Display Impact (130–160mm)
With a substantial size range of approximately 130–160mm, these quartz groups make standout centrepiece specimens, ideal for:
-
Serious mineral collectors
-
Cabinet or shelf display focal points
-
Geological teaching and reference collections
-
Natural décor and conversation pieces
-
Unique gifts for crystal and mineral enthusiasts
The larger scale highlights the complexity of the cluster growth and provides strong visual presence in any collection.
Collecting Interest & Traditional Associations (Non-Medical)
Quartz has been admired across cultures for centuries for its clarity and crystal form. In spiritual traditions, it has been traditionally associated with symbolic clarity and balance, though this listing focuses strictly on the geological and collectible nature of the specimen, with no medical or outcome-based claims.
