Product Description

Introduction: This striking mineral specimen features an elegant composition of sharply defined black pyrite crystals nestled among sprays of glass-clear quartz. Sourced from the renowned Fengjiashan Mine in Daye, China, this piece exudes both visual drama and mineralogical sophistication. Its medium size and intricate geometry make it an ideal centerpiece for collectors and interior stylists alike.

Geological Details: This piece consists primarily of black pyrite (FeS₂) with quartz (SiO₂). The pyrite crystals are sub-metallic, with occasional oxidation or brassy patina, forming well-developed pseudo-octahedra embedded in a matrix of orthorhombic quartz. The specimen formed within a skarn-type polymetallic deposit, a geologically significant environment where hydrothermal fluids infiltrate carbonate-rich host rock, leading to distinctive mineral growth. The Fengjiashan locality is known for producing hematite-rich, pyrite-laced clusters, though specimens with this balance of intact terminations and crystal density remain uncommon.

Aesthetic Appeal: Quartz needles erupt in every direction with clarity and luster, catching light like shards of ice. The jet-black pyrite offers a deep visual contrast—its fractured yet geometric form anchoring the burst of brightness. Under directional lighting, the contrast is heightened, drawing attention to the interplay of rough and smooth, light and dark.

Metaphysical Properties: Pyrite is associated with energy shielding and financial abundance, often referred to as “Fool’s Gold” in folklore. Its grounding nature complements the clarity-enhancing properties of quartz, a mineral known for amplifying spiritual energy and supporting mental focus. Together, this pairing promotes vitality and protection, making the specimen both a display and energy tool.

Rarity: While quartz and pyrite are common globally, the Fengjiashan Mine specimens have gained collector attention for their blackened pyrite and high-clarity quartz. This particular piece's excellent crystal integrity, combined with its rare combination of size, luster, and balanced form, places it in the upper tier of what the mine produces.

Why You Will Love This: Whether you're curating a world-class cabinet or seeking a compelling conversation piece, this specimen captivates with every angle. It’s a sculptural representation of natural power and balance, ideal for display in both minimalist and richly styled interiors.

Collector's Note

Collectors will value this for its representative features of the Fengjiashan orebody, especially the dark-lustrous pyrite and needle-clear quartz. As the mine becomes less accessible, complete specimens of this caliber are becoming harder to acquire, increasing both their visual and investment appeal.

Display Recommendations

Best displayed under warm LED lighting or daylight-balanced spotlights to enhance the reflective clarity of the quartz. Looks exceptional on matte black or walnut wood stands.
