The white fat jade is the gem-grade material of Hetian jade. It is the best of white jade in pure white color. It has the best luster and texture. It is characterized by: warm and firm, pure and pure, white and flawless, like gelatin, hence the name. The simplest way to distinguish this jade from ordinary white jade is to watch it under a white fluorescent light. The white fat white jade is facing the fluorescent lamp, showing a pure white translucent shape with a powdery mist.
The general white jade is translucent to the fluorescent lamp, but it has no powdery sensation. The biggest difference between the two is that, regardless of the grade of the white jade, it is very white to the naked eye, but the fluorescent lamp must have a slight yellowish shade under the fluorescent lamp. Therefore, if there is a slight yellow color under the fluorescent lamp, it cannot be called Sheep fat white jade. The rare and precious sheep fat jade that meets the stringent standards is absolutely inconspicuous. The identification points of the sheep fat jade must meet five aspects, namely, pure texture, fine structure, water head, color white fat, and heavy oil.
1. Pure texture - the mineral content of tremolite in sheep fat jade reaches 99%.
The sheep fat jade exists in the most perfect part of the wall rock alteration. When the granodiorite is in contact with dolomite, a series of contact metamorphic rocks are formed, and the dolomite becomes dolomite marble. The late magmatic hydrothermal fluid along the dolomite marble tectonic fissure channel is metamorphic to form tremolite.
The surrounding rock erosion is transformed into three kinds of lithofacies of dolomite marble-tunnelized petrochemical dolomite marble-metamorphic rock, and the sheep fat jade is found in the tremolite rock facies.
2, the structure is fine - the tremolite in the sheep fat jade is microscopic fibrillar crystallized crystals and aggregates, the crystal size of the tremolite can be determined under electron microscope and optical microscope, the tremolite fiber in the sheep fat jade The length (longitudinal) is 0.033-0.01 mm, and the width (transverse direction) is 0.0006-0.001 mm. These microscopic, fluffy, felt-like tremolite crystals are intertwined to form a pile-like structure, a felt-like structure, and an interwoven structure. Microscopic, fluffy, felt-like tremolite crystal aggregates, characterized by orthogonal polarized light, do not exhibit uniform extinction at the same angle.
3, the head of the water - head, spirituality is the name of jade transparency, in the tremolite jade often from the thickness of 2mm as the standard, white jade in this standard is translucent - opaque, the head of the sheep fat jade shows a translucent .
4, color sheep fat white - sheep fat white is not pure white, but with a lustrous white, some in white can reveal a slight yellow, poor texture can also reveal a slight light gray in white Tune.
5, oily weight - sheep fat jade in the hands of people in the process of continuous touch, self-contained, on the surface of jade produces an "oily" feeling, in some Hetian fine white jade also has this phenomenon, when the sheep fat jade pendant In the water, the jade body is lifted, and the dripping water is not sticky. Therefore, the oily heavy sheep fat is also excellent, and the so-called cotton, which is toughness. Therefore, only the above five aspects are the best good sheep white jade.
Bag Hanger is a most popular gift for women, used for their hand bags when they are in outdoors. There are many shapes for you choice, such as heart shape, round shape and square shape and so on .The material for Bag Hanger is zinc alloy, process should be die casting.
