Brand is just a brand effect. It has nothing to do with the purity of gold. The state has regulations on the purity of gold. Suppose it's four nines. As long as it meets the standards and national regulations.
The purity of gold is actually density, or gold content. At present, there is no 100% pure gold in the world, but at most it is 99.9% (pure gold) and 99.999% (all pure gold hyped by merchants, which is of little significance). These purities are only a few dollars, a 5-gram gold product (about 65438 pounds).
Let me start with a typical case. As we all know, the density is determined by mass (weight) and volume, and the ductility of metals such as gold will occur. For example, a 99.99% gold brick may become 99.95% if you pick it hard with a hammer. This is because the weight has not changed, but the volume has changed.
The reason why the purity of Lao Fengxiang is higher is because of the brand effect of Lao Fengxiang, and the publicity expenses account for a higher proportion. Moreover, the brand should have its own designer, the design fee should account for a certain proportion, and the workmanship should be more elaborate than that of ordinary online stores and professional market stores.
