What should I learn before selling jewelry?

As a salesperson in the jewelry industry, my suggestion is to practice at the counter first 1 month. General salespeople should have a direct understanding of styles, prices and audiences before they can have a say in their future work. You don't need to be proficient in professional knowledge, because jewelry sales are generally in promotion, ordering, channel opening and so on. You need to write a book about the popularity of jewelry, but you need to do it, not read it, read more jewelry magazines and learn about the industry. I wish you success!
