Purple Phantom Fluorite with Cassiterite – Yaogangxian

Discover the captivating allure of Yaogangxian Fluorite Crystal, renowned for its striking purple phantom hues and unique cassiterite inclusions. This specimen features fluorite crystals exhibiting the isometric cubic system, with well-defined edges and a vibrant cubic form. The fluorite’s chemical formula, CaF₂, contributes to its characteristic vitreous luster and a Mohs hardness of 4, making it relatively soft yet durable enough for display.

Originating from the Yaogangxian Mine in Hunan Province, China, this locality is famous for producing diverse and high-quality minerals with complex associations. The deep purple phantom areas within the fluorite crystals add depth and intrigue, while the dark metallic cassiterite inclusions create a striking contrast against the transparent to translucent fluorite matrix. This combination not only highlights the mineralogical complexity but also enhances the overall aesthetic appeal of the specimen.

As a collector’s gem, this piece is valued for its rarity and the distinct mineral pairing uncommon in many fluorite specimens. Its sharp crystal form and vibrant coloration make it an excellent display piece for mineral enthusiasts and geologists alike. To preserve its quality, it is recommended to keep the specimen out of direct sunlight and handle it gently, as fluorite’s relative softness can result in surface scratches or chipping if mishandled.
