Don't be fooled, diamonds and jewels in every store are hand-processed, so it's the same where you buy them. This is just a stunt. Jewelry is made like this. First of all, you have to make a gold seat with a mold (that is, the style you want), and then you can set stones by hand (that is, you can set jewelry on it). Then, you have to manually electrify the gold, manually polish it, and it will become the sparkling jewelry you see now. Every factory does this, so every piece of jewelry in every jewelry store is processed by hand. Jewelry has not been fully mechanized. This is not the focus of buying jewelry, but the grade and technology of jewelry!
