What is Jade?

In a broad sense, jadeite is the commercial name for gem-grade jadeite rock that has commercial value. It is a general term for gem-grade jadeite rock of various colors. The narrow concept of jade refers only to green gem-grade jadeite rocks. In geology, jade is a fibrous aggregate of pyroxene minerals, mainly jadeite minerals, and jadeite rock with chromium as the coloring element. Jadeite that reaches gem grade is very close to the theoretical value of jadeite in terms of composition alone.

What are the types of jade?

Refers to the structure and texture of jade, which is an important indicator of jade quality. The new "species" (also called new mines and new factories, etc.) of jadeite has a loose texture, coarse and uneven grain size, a high content of impurity minerals, and well-developed cracks and microcracks, but its transparency is not necessarily poor. Its specific gravity and hardness are both reduced. The old "type" (also called old mine and old factory, etc.) of jade has a fine and dense structure, fine and uniform grain size, and no micro cracks. It has the highest hardness specific gravity and is of better quality. But transparency is not necessarily good. The new and old types of jade are between the new and old types of jade. They are jade that is residually deposited on the hillside and has not been naturally transported or has been naturally transported a short distance. The new type of jade is the raw material for making B-grade jade.

What is the land of jade?

The meaning of "ground" refers to the cleanliness of the green part of jade and parts other than green, and the degree of coordination between water (transparency) and color, as well as the mutual reflection relationship between "type", "water" and "color". People call "land" "di zhang" or "di zhang". The jadeite and the parts outside the jadeite should be coordinated. If the jadeite is very good, but the parts outside the jadeite have poor water content, impurities and many dirty colors, it is called "good color but poor texture". The water and type of jadeite should be coordinated. For example, if the type is old and the color is good, the water is transparent, and there are few impurities and dirty colors, they set off each other, which is a good foundation. To use a vivid and popular metaphor, the ground is like a piece of land, the seed reflects the looseness of the soil, the green is the crops, and the weeds are impurities, and together they constitute the basic account of jade!

What is Emerald Water?

The water of jade refers to its transparency, also known as water head. The water in jade is related to its structural composition, that is, it is related to its “type”. It is also related to the content of impurities. The better the jade water is, the older it is, the fewer impurities it has, the uniform particle size and the higher the purity.

What color of jade is the best?

Speaking from the perspective of color quality alone, the best colors of jade are emerald green, emerald green, apple green, and yellow vine green. The following are blue-green, violet blue, red jadeite, yellow-green, yellow, blue, gray-blue, etc. Jade jewelry with four or five colors is called five-color jade, which is also very rare. However, this color must be combined with the green of jadeite and a good water quality base, and there must be few impurities and cracks to be priceless.

What is the "python" of jadeite?

On the surface of the jade raw material, weathered and semi-weathered sand grains of the same or lighter color as the surface are arranged in regular and directional shapes such as bands, rings, and blocks. This indicates that the raw stone is locally strongly affected by directional dynamic metamorphism and hydrothermal alteration, which may have released chromium from its interior and caused it to turn green. There is not necessarily green where there is an umbilical cord. Only the appearance of "pine flowers" can indicate that there may be green inside. The presence of scales indicates that the species is old. The python belt is generally parallel to the green direction. The green direction (vein) or green shape is mostly caused by the original cracks filled with chromium.
