和田玉籽料是和田玉最原始的状态，是原石经过山川河流几百甚至上万年的冲刷而形成的玉石，是和田玉中的极品。

和田玉籽料的块度很小，一般为鹅卵石形态，表面比较光滑圆润，带皮色，是大自然中精心挑选的优良玉石。且其为不可再生资源，故具有很高的收藏和把玩价值，仅次于羊脂玉。除白玉以外其他七类要求颜色要从色调、浓度、纯度、均匀度四个方面进行观察分析，颜色色调要正，不偏色，无杂色；浓度的评价是对颜色色彩饱和度而言的，要求浓淡适宜；纯度的评价，一般是越纯正越好，偏色时则较差，如绿色，以正绿为最好，灰绿、蓝绿均较差；均匀度要求颜色要均匀一致。另外，和田玉常常出现两种以上颜色，如带有皮色、糖色时，颜色的搭配好，俏色巧妙或新颖的，可使作品增色，甚至价值倍增。

Hetian jade seed material is the most primitive state of Hetian jade. It is the jade that the original stone has been washed by mountains and rivers for hundreds or even tens of thousands of years. It is the best of Hetian jade.

Hetian jade seed material is small in size, generally in cobblestone shape, with smooth and round surface and skin color. It is an excellent jade selected carefully in nature. And it is a non renewable resource, so it has a high collection and play value, second only to Lanzhi jade. In addition to white jade, the other seven types of colors are required to be observed and analyzed from the aspects of hue, concentration, purity and uniformity. The color hue should be positive, without color deviation and noise. The evaluation of concentration is in terms of color saturation, and the shade should be appropriate. The evaluation of purity is generally that the purer the better, and the worse the color deviation. For example, green is the best, gray green and blue-green are the best The uniformity requires uniform color. In addition, Hetian jade often has more than two colors, such as leather color and sugar color, the color matching is good, and the beautiful color is ingenious or novel, which can add color to the work and even double its value.
