From the point of view of weight: gold metal is actually not a rare substance. It has a large storage volume and a relatively light texture. It is only half the specific gravity of iron, but it is tough and can withstand pulling and beating like copper. Based on this knowledge, when you buy gold jewelry, you should understand that the weight of gold in our hands will be lighter in jewelry of the same size, and it also has better toughness. Second, from the color point of view: gold metal has a silver-gray luster, no matter what polishing method is used, it will not emit too bright color. And it can make a mark. You can hold an edge of the gold jewelry and scratch it on a white ceramic ware or ceramic product, and a black mark will be left. The deeper the mark, the more titanium is contained, and the mark is made by hand. It can't be wiped off. 3. From the perspective of corrosion resistance: We should understand that gold has better corrosion resistance, because there is an oxide protective film on its surface, which will not dissolve even in acid solutions. If it is mixed with other substances, it will be corroded. Of course, it will not blacken like silver and can maintain its own luster. 4. From the point of view of workmanship: when choosing jewelry, its craftsmanship should be exquisite, and the polished surface should be fine and smooth. So no matter what kind of gold jewelry we wear, our skin will be more comfortable. 5. Fire test method (precaution): You can also use fire to test whether it is gold. When burned in fire, gold jewelry will emit a gray luster (for safety, do not use fire test). Other metals will not have this color and produce white or black light.
