1 thought on “Golden bracelet hand knocks on a sound”
Sheldon
The sound of gold knocking is indeed dull, and there is no clear definition of dullness and sharpness, and the methods and angles you knock are different, and the frequency is different. This is not a very rigorous appraisal method. The inside of the bracelet is likely to be hollow, and it will also change the sound of knocking. If you really don't worry, you can go to a nearby detection agency for a test, or drop nitric acid on the gold jewelry, if the nitric acid will produce a green response, then it is no doubt that the fakes are undoubted. There is no chemical reaction on gold jewelry, indicating that your gold jewelry is real gold.
