The so-called python stripes he mentioned were not like stripes; they were more like patches, and there were both white and gray ones.
Python stripes were found on the outer layer of jade rocks, and they were stripes or patches that were different from the rest of the rock. In some cases, they could take up half the rock's surface. They could be grain-like arrangements, or they could be long stripes resembling ropes and coils. The official terms used within the industry were rope, python, or python stripes.
This feature made the rock look ugly, but it was an important clue that indicated whether the rock had good quality jade. Generally speaking, raw rocks that had green on the inside or jade spots that protruded would form these python stripes, so these stripes were actually rather precious.
