I asked my friend to bring a piece of natural jade A from Guangzhou, and when I brought it back, I saw several lines on it. I don't know if it's a stone line or a dark crack.

I only answered it once.

There is no doubt that this thing is true.

More cracks

Good mind

pale

However, because there are many cracks.

Hundreds, not more than a thousand

If you don't understand, please keep asking.

I hope it helps! thank you
