Is the crystal grade 2A or 3A? I don't know. Do not laugh at me.

It should be 3A. Judging from the price, it is 3A.

Crystal classification:

AAA grade: The whole crystal is transparent and flawless inside and outside, and the surface has no man-made defects visible to the naked eye.

AA level: there are tiny flaws, or tiny natural inclusions, clouds or flocs not exceeding 3mm.

Grade A: There are slight flaws, and clouds or cotton wool can be easily seen by naked eyes.

Class AB: There are big cloud inclusions, small ice cracks and small scratches on the surface.

Grade B: More than half of the whole crystal is cloud-like and inclusion, with large ice cracks and small cracks on the surface.

Grade C: the lowest grade, cloud-shaped, with obvious ice crack marks and obvious cracks on the surface, which seems to be broken at any time.

Therefore, if there are many cracks and the range is large, be careful not to bump into each other. If it is small, it will be fine, and it will not be broken.
