About this specimen

Cassiterite, renowned for its glossy and elongated form, hails from the famous Yaogangxian Mine in Chenzhou, Hunan Province, China. This mine is well-known among mineral collectors for producing high-quality specimens with exceptional crystal habits. Cassiterite crystallizes in the tetragonal system, typically presenting as prismatic or elongated crystals, and has a Mohs hardness of 6 to 7, making it relatively durable for display.

This particular specimen exhibits a striking metallic luster with a deep brown to black coloration, characteristic of cassiterite from this locality. Its elongated crystal form highlights well-defined edges and smooth, glossy faces, reflecting light beautifully. The crystal is opaque with minor translucency along some edges, emphasizing its natural formation without any artificial enhancement.

As a collectible mineral, cassiterite from Yaogangxian is valued for its rarity and the quality of its crystal development. The specimen’s distinctive elongation and lustrous surface make it an excellent choice for collectors seeking representative examples of tin oxide minerals. Proper care involves avoiding prolonged exposure to moisture and handling the specimen gently to preserve its glossy finish and sharp crystal edges.
