Question: I recently customized a batch of alloy jewelry, but told me that the material of the jewelry is copper. I also said that copper is of higher grade and higher cost than alloy. Is that true? Answer: The jewelry factory is right. Copper jewelry is indeed higher grade than alloy jewelry, and the cost is a little higher. At the same time, copper jewelry can achieve a level of exquisiteness that alloy jewelry cannot achieve. The alloy jewelry you originally customized may be because the alloy can't produce the desired jewelry effect, so you replaced it with copper. If the jewelry factory did not increase the price of the jewelry, you should be cheating. The information comes from the Internet, please contact if it involves infringement.
