If a jade clasp you just bought has scratches on the mirror, it doesn't necessarily mean it's fake. Jade is a polycrystalline structure, so it will show different luster and texture under different light angles, sometimes giving people a sense of scratches. In addition, improper operation may also lead to scratches on the jade surface during processing.
However, if you suspect that the jade buckle you bought is a fake, you can make a preliminary identification by the following methods:
1. Observe the jade surface with a magnifying glass to see if there are bubbles or cracks. Real jadeite has a smooth surface without bubbles and cracks.
2. Touch the jade surface with your hands to feel whether its texture is smooth. Real jadeite is delicate and comfortable to the touch.
3. Observe whether the color and texture of jadeite are natural. Real jadeite has natural color and clear texture.
4. smell it. Real jadeite has no peculiar smell. If it has peculiar smell, it may be a fake.
If you suspect that the jade buckle you bought is a fake, I suggest you go to a professional jewelry appraisal agency for appraisal.
