How to define the perfection of jadeite?

You will often see sellers of finished jade products say that a certain piece of jade is perfect, or absolutely beautiful. So what is the definition of perfection? Many people think that perfection means having no flaws at all. What does it mean to have no flaws at all? Is it completely transparent? Or do you want full color?

Because defects and flaws in jade finished products are two different things, defects are of course more serious in comparison. So the jade industry's definition of a perfect finished product is mainly based on the following points.

First of all, there must be no cracks. The cracks here refer to small cracks in addition to large cracks. There are no large stone lines, just a very thick line. Small stone lines are acceptable. There are no sand holes, no coarse structure, and no severely petrified moss. Relatively speaking, if there are cotton, small stone lines, some black spots, gold sprinkled, and other minor defects, we think they are within the tolerable range.

That is to say, even if there are such things, we can still call them perfect, but the definition of perfection is actually different in everyone's mind. Some people may not accept any cotton at all, and they think that having cotton is imperfect. But how is it possible for natural things to not have any cotton at all?
