About this specimen
Discover the mesmerizing allure of this rare Chinese crystal specimen, featuring a unique Yaogangxian quartz cluster with stunning cassiterite and purple fluorite elements. Perfect for collectors and enthusiasts, this extraordinary mineral piece is a testament to nature's artistry.
Originating from the renowned Yaogangxian Mine in Hunan Province, China, this specimen showcases a remarkable assemblage of minerals prized for their distinctive qualities. The quartz crystals, belonging to the hexagonal crystal system, exhibit a vitreous luster and transparent clarity, forming an elegant cluster that serves as the foundation for the cassiterite and fluorite.
Cassiterite (SnO₂), a tin oxide mineral with an orthorhombic crystal system and a Mohs hardness of 6 to 7, appears here as lustrous, deep black crystals contrasting sharply against the clear quartz. Complementing this is the rare purple fluorite (CaF₂), known for its cubic crystal system, brittle tenacity, and a Mohs hardness of 4, displaying a delicate translucency and vibrant coloration that enhances the overall aesthetic.
This specimen’s combination of textures and colors—clear quartz, jet-black cassiterite, and subtle purple fluorite—creates a visually striking piece ideal for display. The Yaogangxian Mine is celebrated among mineral collectors for producing such complex and well-formed specimens, adding to this cluster’s desirability and collector value.
For preservation, it is advisable to keep the specimen away from prolonged exposure to direct sunlight to prevent any potential fading of the fluorite’s color. Handle with care to avoid damage to the more fragile fluorite crystals, ensuring that its natural beauty endures in your collection.
