Horrible they had my package for 6 days just to tell me that it had been stolen on the way there smh no sounds like to me yall are stealing the items. Why did it take so long to tell us that it had been stolen smh. I dont know why ebay still using yall. I recommend nobody use ebay authentication for jewelry. This place is horrible a joke.
