Pakistani Black Tourmaline on Albite specimens are prized by mineral collectors worldwide for their striking contrast between jet-black schorl tourmaline crystals and bright white to grey albite feldspar matrix. Sourced from the mineral-rich pegmatite deposits of Pakistan — particularly Balochistan and Khyber Pakhtunkhwa (KPK) — these specimens showcase millions of years of geological artistry.
Key Visual & Physical Characteristics
- Colour Contrast: Lustrous black tourmaline (schorl) crystals set against a bright white or silvery albite matrix create a dramatic, high-contrast display piece.
- Crystal Form: Tourmaline appears as elongated prismatic columns, often striated lengthwise, with well-defined terminations.
- Matrix Quality: The albite host rock is typically well-crystallised, adding textural interest and structural stability to the specimen.
- Luster: Tourmaline exhibits a vitreous to resinous luster; albite displays a pearly to vitreous sheen.
- Natural & Untreated: Specimens are 100% natural, unheated, and chemically untreated.
Primary Localities in Pakistan
- Balochistan Province: Known for producing bold, well-formed schorl crystals on contrasting white feldspar matrix.
- Khyber Pakhtunkhwa (KPK): Yields fine pegmatite-hosted specimens with sharp crystal definition and aesthetic matrix presentation.
