Exceptional Hauyne & Pyrite Specimen from Afghanistan (87.35 ct) For Sale

Description :Among modern mineral finds from the Hindu Kush region, Afghan specimens continue to stand out for their sharp crystallization, vivid color contrasts, and aesthetic matrix associations. One such remarkable piece is a combined hauyne and pyrite specimen weighing 87.35 carats, originating from Afghanistan, with overall dimensions of 27.40 × 22.75 × 14.23 mm.
Overview of the Specimen
This piece brings together two minerals that rarely share equal visual attention in the same hand specimen:
Hauyne: A rare feldspathoid mineral known for its deep royal-blue to bluish-green coloration. It is highly sought after by collectors due to its intense color saturation and limited occurrence in gem-quality form.Pyrite: Commonly known as “fool’s gold,” pyrite provides a striking metallic contrast, often forming cubic or striated crystals that enhance the visual geometry of mineral specimens.
When combined, these two minerals create a natural contrast of luster vs. color, and metallic gold tones vs. vivid blue hues, making the specimen visually dynamic even at a small scale.
Aesthetic and Structural Characteristics
At just under 3 cm in length, this is a compact but highly detailed specimen. The proportions (27.40 mm long, 22.75 mm wide, 14.23 mm thick) suggest a slightly flattened crystal cluster, likely formed in a confined cavity where both minerals had space to crystallize simultaneously.
Key visual features likely include:
Sharp pyrite crystal faces reflecting light with a brassy metallic sheenEmbedded or adjacent hauyne crystals showing intense color zoningNatural matrix support binding both minerals into a single coherent formationHigh contrast between opaque metallic and translucent vitreous phasesGeological Significance
Hauyne typically forms in silica-undersaturated volcanic environments, while pyrite can form in a wide range of hydrothermal conditions. Their coexistence in a single specimen suggests a complex mineralizing environment, possibly involving multiple stages of fluid activity.
Afghanistan’s pegmatitic and metamorphic terrains are known to produce such multi-phase mineral assemblages, where late-stage hydrothermal fluids introduce sulfides like pyrite into earlier silicate formations.
Collector Value
For mineral collectors, this type of specimen is valued on several levels:
Rarity of hauyne in collectible crystal formStrong visual contrast with pyriteCompact display size suitable for cabinetsInternational provenance from a well-known mineral region
The 87.35 ct weight also places it firmly within the “cabinet miniature” category, making it ideal for display without requiring large space.
