Shijiangshanite
1 in the gallery
Shijiangshanite is a lead-calcium-aluminum silicate that forms as crystals in hydrothermal environments. It typically exhibits a light to pale blue-green coloration and can present a platy to tabular habit with a vitreous to pearly luster that highlights its delicate crystal faces. The mineral’s formula indicates the presence of hydroxide groups and water, reflecting its hydration in its natural state. Notable specimens have come from China, where specific hydrothermal settings and mineralizing fluids have favored its crystallization, often in association with other lead and silicate minerals.

Where Shijiangshanite is found
About Shijiangshanite
Collectors value Shijiangshanite for its rarity and its characteristic appearance, including its color and crystal habit, which contrast with more common lead-containing minerals. The combination of its size, form, and local geological context makes it a compelling piece for display and study, emphasizing the diversity of silicate minerals produced in hydrothermal systems. While not widely distributed, specimens from Chinese localities are sought after for their clarity and the way they capture the mineral’s subtle hues and light interaction.
