Yves Saint Laurent Amour

I am in love with this ring the minute I saw it like 3 years ago (maybe?) And I still can't get it out of my head! I still can't decide which color I like the most but maybe this is the winning one ... but I am so unsure!!! I want to be 100% sure to buy it because is not easy for me to return it at all (Yes, all the mailing and stuff) So still I can dream with having it... very soon !
