Bismuthinite Crystals – Acicular Form – Inner Mongolia, China

Imagine the mesmerizing allure of deep gray crystals, etched with intricate patterns, straight from the mineral-rich landscapes of Inner Mongolia, China. These striking bismuthinite crystals are a must-have for mineral enthusiasts and collectors seeking unique geological treasures.

Bismuthinite is a sulfide mineral with the chemical formula Bi₂S₃, crystallizing in the orthorhombic system. It typically exhibits a metallic luster and a Mohs hardness of 2, making it relatively soft and requiring careful handling. This particular specimen features a rugged morphology with dark gray to nearly black crystals, showcasing well-defined, elongated prismatic forms characteristic of bismuthinite. The intricate surface patterns highlight the mineral’s natural growth and structural complexity.

Originating from Inner Mongolia, a region known for its diverse and mineral-rich deposits, this specimen reflects the geological uniqueness of the area. The locality is respected among collectors for producing fine-quality sulfide minerals, adding provenance value to the piece.

Weighing approximately 220 grams and measuring about 92x42x63 mm, this specimen is ideal for display, offering both aesthetic appeal and scientific interest. Its rarity in such well-formed crystal aggregates enhances its desirability among collectors and crystal enthusiasts.

Due to its softness and metallic luster, it is recommended to handle the specimen gently and avoid exposure to moisture to preserve its surface integrity over time.

China — dominant modern source for collector-grade specimens since the 1990s.
