I can't say I've bought anything from this seller but I checked out the link. It doesn't exactly sell me on the product and if it's as good as it says it is why is it only 59 bucks normally an on sale for even less ? I didn't quite agree with their whole CZ and Moissy comparison. I don't own a Moissy but from what I've read about them over the months I get the impression that a Moissy isn't pretending to be something it's not. It's its own gem in every way where as a Cz is actively trying to fool the rest of the world. I also know that there have been some advances in Moissy lately so if you find a good seller you may not suffer any yellow or green tinges in your Moissy at all.
I have spent more than one full year doing research on diamond alternatives and I can say with confidence that for me personally (wanting a sim) I'm going with Asha from BDT although there are other vendors out there for them. They aren't the most expensive and they are very up front and honest which I like.
I've also read over the months about various E-bay scams too when it comes to rings and not getting what you think you paid for so it's risky to any potential buyer as you can never really know what you're getting. If you are having trouble clicking that " buy now" button then I would wait , your gut might be trying to tell you something about that e-bay vendor.
If you do decide you want to take my advice and see what this Asha is about the Asha forum is a great place. When I was discovering what I really wanted for a diamond I lurked for more than a year reading what women had to say about Asha and they are a great bunch of people very friendly and very generous with real life pictures of the stones. Couldn't ask for a better Forum crowd.
