I bought a necklace from them before last Christmas. Overall the experience was not too bad, but not the greatest either. The reason I chose that Site was because it was in my local area. I wanted to visit to choose the necklace myself, but I was told that this was not possible.
For the money the quality was ok I guess. But the claim that they are the best pearls available is a little farfetched I feel. The pearls were a little on the chalky side and all the pearls in the necklace had marks. My mom was happy though, and I guess that is what is most important.
I bought another strand on Valentine's for my g-friend from another online website and the quality was a lot better - or I should say I let my g-friend choose the website and necklace she wanted. I do not remember for sure what company it was, I will ask her and let you know. The value for the money was definitely better there.

One last thing. I bought a strand that was listed as AAA+ from premiumpearl and a strand that was only AA+ from the other website. I only know about pearls what I learned on this forum when I was looking to buy, but I think AAA+ is madeup because the AA+ was way better, but a grade lower. Go figure.
