Stibnite Acicular Cluster, Lengshuijiang Mine, Hunan

Stibnite dazzles with its acicular formations, sourced from the renowned Lengshuijiang Mine in Hunan, China. This stunning mineral showcases needle-like crystals, making it a prized addition for collectors and mineral enthusiasts.

Stibnite (Sb₂S₃) crystallizes in the orthorhombic system and exhibits a metallic luster that enhances its dramatic, elongated acicular crystal habit. With a Mohs hardness of 2, these slender, radiating needles display a striking lead-gray color that often reflects subtle iridescence on fresh crystal surfaces. The crystals are opaque, forming a dense, intertwined cluster characteristic of specimens from the Lengshuijiang locality, one of the world’s most significant antimony sulfide mining regions known for producing fine quality Stibnite specimens.

This cluster’s aesthetic appeal lies in the sharp, needle-like crystal formation and the brilliant, reflective surfaces that catch light from multiple angles. Its provenance from Hunan Province adds to its collector value, given the region’s reputation for producing some of the finest acicular Stibnite worldwide. Such specimens are sought after not only for their scientific interest but also for their striking display presence in mineral collections.

Due to Stibnite’s relatively low hardness, care should be taken when handling or displaying this specimen to avoid damage to the delicate needles. It is best kept in a stable environment, away from excessive humidity and mechanical stress, to preserve its natural luster and intricate crystal form.
