Composed primarily of calcium-magnesium silicate (Ca₂(Mg,Fe²⁺)₅Si₈O₂₂₂), with tremolite content exceeding 90%. Density ranges 2.90-3.10 g/cm³, Mohs hardness 6.0-6.5, formed through hydrothermal alteration of dolomite over 700-800 million years.
Natural inclusions like chromite and graphite create color variations (white, green, black).
Xiuyu Jade
Silicate-based with quartz and limonite impurities, Mohs hardness near 7, predominantly green due to mineral composition.
Historical & Cultural Context
Hetian Jade
Used for tools and ritual objects since the late Neolithic Age, symbolizing power in Shang-Zhou dynasties. The “Five Virtues” philosophy (benevolence, justice, wisdom, courage, purity) crystallized during the Han Dynasty.
"Seed material" from the Yurungkash River became a Qing imperial favorite for its weathered texture.
Xiuyu Jade
Mined in Sichuan' s Xiushan, gained prominence in Ming-Qing periods for its jadeite-like green hues, often carved into scholar' s objects.
