If you want to make friends with some jewelry designers, please search their contact information on "Shenzhen Jewelry Talent Network", register for free in various jewelry forums, communicate and seek help.
But as jewelry designers, many people don't like to exchange relevant skills and experience with strangers. Even if you can find him on QQ, you may not be able to chat as you wish. A real designer has a strong personality, has his own design concept for many years, and is also very selfish. As for jewelry forums, most of them are jewelry designers with working experience ranging from/kloc-0 to-3 years. Experts generally have no time to chat on it, and they are not interested in showing anything on it.
After reading your message, I answered it according to my own opinion. I dare not say that I am a master among masters. After all, seven and a half years of jewelry design experience tells me that this industry is such a thing. Ha ha!
