Place of origin:
Yufeng Mountain in Kunshan City, Jiangsu Province
Mineral composition:
Dolomite and silicilate
Produce in Kunshan, Jiangsu province, Kun rocks are made of berg crystal formed in dolomite from siliceous liquid that filled the holes and tissues of the rock. To make them suitable for display is quite complex. The quality of Kun rocks only becomes evident after prolonged exposure to the sun for five to six days followed by repeated washing of the mud in the holes. After hundreds of years of extraction, they have become quite rare and successive governments have banned their mining for fear of mountain erosion.
