A rare form of Lingbi stone with siliceous or calcareous-siliceous concretions that are milky white to beige in color. The whitish portions were formed from ancient phytolites that were covered with calcareous-siliceous deposits. The whitish portions of these stones were formed before the darker base material. They were formed about 900 million years ago. White Lingbi comes from Panshi Mountain in Lingbi County in Anhui province.
