Chemical Composition and Formation Process

Shoushan Stone, a type of pyrophyllite, primarily composes of aluminum silicate hydroxide with the chemical formula Al₂Si₄O₁₀(OH)₂. It forms through the metamorphism of sedimentary rock, where the original minerals undergo physical and chemical changes due to heat and pressure, often in the presence of water. The unique combination of trace minerals present during formation give Shoushan Stone its wide range of colors, including white, red, light blue, and more.

Name

The name “Shoushan Stone” derives from its primary source, Shoushan Mountain in the Fujian Province of China. Alternative names include “Snakeskin Jasper” due to its often patterned appearance that resembles the skin of a snake. The variations in color and pattern lead to further specific names within the category, such as “White Shoushan,” “Red Shoushan,” and “Blue Shoushan.”

Mythology and Legends

Shoushan Stone has been historically significant in Chinese culture, often associating with the imperial court. It was valuable for carving imperial seals and other artifacts. In Chinese mythology and literature, it is a stone of scholarly virtue, embodying purity, wisdom, and elegance. In Feng Shui, the stone brings balance, peace, and good fortune to the household. It is often used in carvings placed in homes or offices to attract positive energy.

Mining, Production and Use

Shoushan Stone has been mined for over 1,500 years, with its use documented as far back as the Tang Dynasty (618-907 AD), predominantly in the Shoushan Mountain area, with early extraction methods involving simple tools and manual labor.
Today, it is still primarily sourced from the Fujian Province. Modern mining techniques involve more advanced machinery to extract the stone more efficiently while still preserving its natural beauty. Strict regulations are in place to manage the sustainable extraction of this culturally significant resource.

The process of creating beads from Shoushan Stone involves cutting the raw stone into smaller pieces, which are then shaped into round beads through grinding and polishing. The beads are drilled and further polished to achieve a smooth finish suitable for jewelry. Beyond beads, Shoushan Stone is renowned for its use in intricate carvings, including figurines, seals, and other decorative items. Historically, it has been used to make seals for officials and emperors, and today it continues to hold cultural significance in China.
