About this specimen
Gypsum is renowned for its striking needle formations, showcasing radiating spherical clusters from the mineral-rich region of Guizhou, China. These natural formations are perfect for collectors or as a unique decorative display, highlighting the beauty of Earth's geological processes. This specimen exhibits the monoclinic crystal system characteristic of gypsum, with a Mohs hardness of 2, making it relatively soft and easy to handle with care. Its chemical formula, CaSO4·2H2O, reflects its status as a hydrous calcium sulfate mineral.
The specimen features delicate, slender needle-like crystals arranged in radiating clusters, displaying a gentle translucency and subtle vitreous to silky luster. The color ranges from a soft white to pale cream, emphasizing its natural purity and unaltered state. Originating from Guizhou, a well-known locality for quality gypsum specimens, this piece offers a clear representation of the region’s distinctive mineralogy.
Collector value is enhanced by the rarity of such well-preserved, radiating spherical clusters, which are less commonly encountered in gypsum specimens. Its aesthetic form and natural arrangement make it an excellent choice for display, appealing to those interested in earth science and mineralogy. Due to gypsum’s softness, it is advisable to handle the specimen gently and avoid exposure to water or prolonged humidity, which may alter its surface or structure over time.
