The value of yellow wax stone, also known as Longwangyu, is named after the waxy texture on the surface of the stone. The market price is usually around 80~ 1000 yuan a gram. Chrysotile asbestos is a mixture of quartzite minerals and acid soil due to geological changes, natural conditions such as geothermal or volcano near acid soil, and long-term catalytic metamorphism by the temperature of acid soil and geothermal volcano.
Because of its unique formation, chrysolite has the color of Tianhuang and the hardness of jadeite. It has the characteristics of compact structure, strong toughness, good hardness, high transparency and rich colors. It is mainly used as a sculpture of Yin Zhangshi.
Chrysolite belongs to quartzite, which is mainly divided into seed material, mountain material and landscape material. The seed olivine is of the best quality and the most valuable. Seed crystal olivine, also known as water material, is formed by the long-term rain erosion of the original rock. Therefore, the seed olivine is mostly round or oblate, which has the characteristics of high cleaning degree, fine moisture and stable jade, and is the first choice for sculptors.
The germplasm seed material of yellow wax stone is mainly produced in Lingnan and Yunnan, among which the yellow wax stone in Lingnan is the most famous, which has the characteristics of strong gem luster, delicate texture, full toughness and bright color, and is a treasure of yellow wax stone.
Huang Longyu, a representative variety of yellow wax stone produced in Yunnan, is highly praised by many merchants and collectors for its delicate stone quality and moist color, which has promoted the "yellow wax stone fever" all over the country and made yellow wax stone officially listed in the national jewelry and jade list.
The main component of yellow wax stone is silicon dioxide. According to the purity and particle size of silica, chrysolite can be divided into frozen wax, colloidal particles, fine wax, crystalline wax and coarse wax. Among them, the grade of frozen wax chrysolite is the highest, and it is transparent or translucent. Under the irradiation of flashlight light, yellow wax stone can penetrate into solid or even transparent, and has the characteristics of smoothness, oiliness and cleanliness.
