I have found quality control to be very poor. Recently received a pendant with a crack through the middle of it. The crack appeared to be old, as it was brown on the back of the stone. Also received several pieces over the past few months with gross manufacturing defects. Have received plastic bags of jewelry that are dusty and dingy.
Smart Labels are often charged to the customer, regardless of whether the item they are returning is damaged/broken/defective. It does not build customer loyalty to charge a customer to return an item that is defective.
Customer service representatives are sometimes not professional and don't do everything they can to help the customer. I have had experience with rude and unprofessional representatives.
Hosts often act like the Beverly Hillbillies. This detracts from the credibility of the company.
Returns take way too long to process. Even orders take too long sometimes. Have been waiting for a pendant to ship since I ordered it on 10/20 and it still hasn't shipped yet. It is 11/2. That is 12 days. Returns take forever. If you are lucky enough to get a refund, it is almost always just a partial refund.
Can't trust quality. Since returns are such a pain in the butt, if you don't get something that is right (either damaged or ugly), you can pretty much expect to eat the loss.
