Yellow wax stone, also known as Longwangyu, is named after the waxy texture on the surface of the stone. It is because of geological changes that quartzite minerals are mixed into acidic soil, and there are natural conditions such as geothermal or volcano near acidic soil, which has been catalyzed by the temperature of acidic soil and geothermal volcano for a long time and deteriorated to form olivine.
High-quality yellow wax stone has a yellow color and jadeite hardness, good hardness, high transparency and rich colors.
Lingnan area is the earliest place to appreciate the yellow wax stone in the state-owned history of China.
