I've been shopping in this store for years, they have a store mostly where the airport is.. Judging from the price, u can absolutely tell that it is not real jewelry. As you said, your bf is good with buying real jewelry., how come he did not notice that what he was buying is faux. I mean come on? From that price even if you said it's $800 ( although you originally said that ur bf paid $100) you can never ever get a real good quality pearl for that price. A cultured pearl would cost you approximately around around $5000 & up. It seems to me that you are yourself, doesn't know good jewelry. I had been buying in this store for years like I said, & I have almost everything that they have , but never heard about this $800 pearl necklace that you are talking about. I even called the customer service because now I am very very curious if this necklace does exist.
A lot of people like me, who owned real good jewelries, love this store., because I can travel & have fun with it. & no matter how much the price they are charging, it's absolutely nothing compare to a real jewelry.
So my advice is either your bf lied to you about everything, or he's really cheap.. Who cares if he buys u a fake jewelry? !!
Before making a comment on a store or anything, do ur research. Educate yourself about real & fake because it seems to me that you don't even own a real jewelry!!!!
