This year, my mom and aunt, instead of giving me a gift gave money ($300) to get what I want.

I want a pair of golden south sea pearl earrings (studs) I saw them on someone else, and I love how they look! and they go with almost anything.

the problem is, it is really hard to comparison shop, since each merchant uses their own grading system and I don't know their reputability and am not willing to put as much research into this as we did for my engagement ring. But I want a good value.

Anyway, I am thinking of buying this one:

They seem to be cheaper than many other places. Is this because they are in China and willing to have a lower profit margin than "western" retailers? or is it the quality? It can easily be both. Very hard to know.

same kind of earrings in another store:

If anybody has more knowledge or experience, or can recommend a retailer, please feel free.
