There are clouds in the sky and stripes on the stones. If only it were streaking. If it is cracked, it will be expensive. Teach you a trick to identify stone lines or cracks. Scrape the stone surface slowly with your nails. If there is a card at the stone grain, it is a crack. Realistically speaking, just buy and wear it. If there is no problem, 8000 yuan may not be available. If you buy it and wear it, it will be OK if you look good. Even if you spend 1 10,000 on a piece of jade, it will not be perfect. Because100000 is more perfect. Ha ha!
