It may be the so-called "Vietnamese Sha Jin" necklace that is popular in the market, which belongs to a copper alloy. Its main ingredient is brass, and the content of sand gold is very low, usually less than 5%, ** very cheap, and is mostly sold in cultural markets or city markets.

It may be that the necklace your boyfriend brought hasn't been cleaned in a long time. I haven't brought it for a long time, and it smells like patina.

Fake, not real gold necklace, you can quietly use a magnet to try to attract no, if it is real gold, it will definitely not have a metallic taste.

Hello, the gold necklace will smell rusty and cannot be used as a basis for judging the authenticity of the necklace.

Because gold necklaces need to be welded many times during processing, some gold chains with unclean solder will indeed have a rusty smell.

Judging that the gold necklace can be detected by the following methods: 1. Burn it with fire: burn the gold necklace red with fire, and watch the color change of the Kuzhou Registry Hall after cooling, if the surface is still the original ** color is pure gold.

If the color is darkened or darkened to varying degrees, it is not pure gold. Generally, the lower the fineness, the stronger the color, and all of them turn black, indicating that it is fake gold jewelry. However, this method of judging is not absolute, because there will be a situation where the real gold necklace is mixed with some fake gold.

Second, the orange plum will send the Zhaowu necklace to a professional testing institution, such as the gold and silver jewelry quality inspection center, with professional equipment for the best color and weight testing, such testing is the most professional. The test result will also be reported by the test reporter, and the test requires a testing fee of 50-100 yuan. This kind of money costs some money, but the results are much more accurate than the first one.

I just used a hyperbaric canister gun. It has never melted after burning, but its color is black and golden, and it only melts a little.

There will be some fake gold mixed in the necklace.
