The overlooked important quality of jade

When talking about jade, people can talk about its type, water and color. However, there is a factor that seems insignificant but actually affects the quality of jade. This overlooked detail is the uniformity of jade. Uniform means that the quantity distributed or allocated in each part is the same; the size, thickness, and time intervals are equal.

Uniformity of seed

The size and density of jadeite grains determine its transparency. The unevenness of the species can be discovered by the difference in transparency, that is, from the perspective of naked eye observation, the unevenness of the species is determined by observing whether the transparency is consistent. Ice and glass types are extremely transparent, and uneven textures can be easily observed with the naked eye. The grains of the glutinous variety are relatively coarse and less transparent. Different parts may appear slightly transparent or opaque, which is an uneven surface, but it is not difficult to distinguish with the naked eye. On the contrary, those jades of inferior quality have coarse grains, loose structure, and are basically opaque. The coarse grains make it difficult to distinguish with the naked eye.

Uniformity of color

Common colors of jade are green, yellow, red, purple and white, and the uniformity of jade color is mainly reflected in the uniformity of jade chroma and color distribution. Regardless of whether green is positive or negative, if there is no color difference in the chromaticity over the area where its color is distributed, then its uniformity will be consistent. The greater the color difference, the worse the uniformity. As the green extends, the changes in depth and lightness will make the green show obvious gaps and layers, making the green extremely uneven. At the same time, white cotton and other colored cotton and impurities attached to the green rob the green of its uniformity.

Uniformity of color tone

Hue refers to the tendency of a certain color shown in the overall appearance of jadeite. The hue is affected by many other factors of jade, such as magazines, cotton spots, and color. Among them, color has the greatest impact. The uniformity of color tone can be observed from two different distribution states, one is on the surface and the other is deep inside.

surface

On the surface and basis of color tone of jade, other colors will grow more or less. For example, the color tone and the attached color will dissolve and dilute each other at the attached part, making the color of this part change to become thicker or lighter. Local color transformation aggravates the unevenness of color tone. On the contrary, the color tone and the attached color will repel each other, such as dirty color and mottled color, which will also manifest as uneven color tone.

internal

Everyone is familiar with the colors that penetrate deep into jade, such as floating flowers. Typical floating flowers are green or blue bands, blocks or clusters. Clear water has a light green tint, the color blends in with the species, it is fresh and elegant, and is known for its good uniformity; blue water has a blue hue, which can be light or dark, and is also very uniform.

Therefore, when purchasing jadeite, you should not only pay attention to the conventional factors such as type, water, and color, but also pay attention to the uniformity of jadeite, which can also reflect the quality of jadeite!
