After buying gold, you can verify it in the gold shop. After I bought the gold jewelry myself, I don't feel at ease to verify it on the spot. Fired with a professional high-temperature musket, the real pure gold jewelry remains unchanged. If you buy it online, you can also get it to a local physical jewelry store. Please ask the staff to use a high-temperature musket to help verify. If an individual runs a gold shop, he must have this qualification and the skills to identify the authenticity of gold. Because, if a guest asks a related question and can't answer it, then the guest will doubt the authenticity of the gold ornaments in this gold shop, and the chance of buying things in the store will be very small. Not to mention the gold shop opened by a jewelry company.
