“"Wulfenite loves... cerussite" China entered the small circle of countries producing the best wulfenites at the end of the 20th century. It quickly found its place thanks to the beautiful crystals from the Jianshan Mine (Ruoquiang Co., Bayin'gholin Autonomous Prefecture, Xinjiang). They are bright orange to red, sometimes reaching 4 cm in length. Around 2010, this deposit was singled out by a discovery, small in number of specimens but important by its quality: flat crystals of orange wulfenite covered by cerussite, except for their edges. The contrast and the aesthetic are striking. This specimen from the Sorbonne University collection is the largest known to date.”
