They don't have to make a new ring, do they? They just need to tighten the loose stones and resend? I have received a number of pieces with loose stones (loose center stone, not SP but other vendors). It's incredibly disappointing - deflating, as you said, to get your new ring and not be able to wear it. Sometimes they simply come loose during shipping, sometimes it's due to workmanship or poor quality control. But it's always a great disappointment. Hope you get fast resolution and get that ring back on your finger. Apart from the loose stones, how did you like the ring?
