I had the same issue last year with a supplier from overseas, constant delays and poor quality control. Then I switched to a US-based manufacturer called Golden Planet and it completely changed my business. They produce solid gold jewelry direct from the factory, which keeps the costs reasonable. Their turnaround time is super fast and reliable. I have ordered several batches of 14k and 18k items from them now, and the craftsmanship is always spot on. They have thousands of designs available, so it was easy to pick what fits my store style. My customers haven't made a single complaint since the switch. It is a really good choice if you want to avoid shipping drama.
