Mineral Species & Scientific Classification

The primary mineral in this specimen is Black Tourmaline, most commonly the species Schorl, a member of the tourmaline supergroup.

Primary Mineral: Schorl (Black Tourmaline)
General Formula: NaFe₃Al₆(BO₃)₃Si₆O₁₈(OH)₄
Mineral Group: Cyclosilicate (Borosilicate)
Crystal System: Trigonal
Hardness: 7–7.5 Mohs
Lustre: Vitreous

Associated Minerals:
Quartz – Silicon Dioxide (SiO₂), trigonal crystal system
Feldspar – Tectosilicate group (commonly microcline or albite in pegmatites), monoclinic or triclinic systems

Black tourmaline typically forms elongated, vertically striated prismatic crystals. Quartz appears as clear to milky prismatic crystals with hexagonal symmetry, while feldspar commonly occurs as blocky, tabular or massive pale-toned crystals.

Geological Formation – Skardu Pegmatite Fields

The Skardu region of Gilgit Baltistan lies within the Karakoram and Himalayan orogenic belts, an area renowned for complex tectonic activity and world-class pegmatite mineralisation.

This specimen likely formed within granitic pegmatites, which are coarse-grained igneous bodies enriched in volatile elements such as boron. Pegmatitic environments provide ideal conditions for the crystallisation of large, well-formed minerals.

Formation process:

• Intrusion of granitic magma

• Slow cooling allowing large crystal growth

• Concentration of boron-rich fluids

• Crystallisation of tourmaline alongside quartz and feldspar

Black tourmaline crystallises early in boron-rich pegmatitic systems and may be embedded within quartz-feldspar matrices, creating striking mineral combinations.

Crystal Habit & Visual Characteristics

This Grade A specimen displays natural crystal growth of black tourmaline in association with quartz and feldspar matrix.

Typical features may include:

• Elongated prismatic black tourmaline crystals

• Vertical striations along crystal faces

• Contrasting light feldspar host rock

• Clear or milky quartz crystals

• Strong colour contrast between dark and pale minerals

The black coloration of schorl is caused primarily by iron content within the crystal structure. Surface lustre is vitreous, and crystal terminations may be flat or subtly pyramidal depending on growth conditions.

No artificial treatments or enhancements are implied; this is a natural mineral specimen.

Collectibility & Display Appeal

Mineral combinations from Skardu are internationally recognised for quality and crystal definition. The association of black tourmaline with quartz and feldspar is classic for pegmatite mineralisation and offers both aesthetic and geological interest.

Collectors value these specimens for:

• Recognised Himalayan pegmatite locality

• Classic tourmaline crystal habit

• Multi-mineral contrast

• Strong geological context

The combination of dark schorl with pale feldspar and clear quartz provides a balanced and visually appealing display specimen suitable for mineral cabinets, geological collections or educational use.

Black tourmaline has been traditionally associated in various cultures with protection in a spiritual sense, though this listing focuses entirely on mineralogical and geological characteristics.
