Jewelry Boutique

Sorry for the caps, it just gets people's attention. Only one person had answered my previous question, and their answer made no sense what-so-ever. I can't pick which necklace and earring combo to buy. When I was trying to narrow it down, people were being rude and saying I was a spolied brat, but I have to buy this stuff because I'm *highly* allergic to earrings that aren't quality made. It's some material in it.
Anyway, which do you like better?

One (Tiffany & Co.): http://www.tiffany.com/Shopping/Item.aspx?fromGrid=1&sku=23900564&mcat=148204&cid=287464&search_params=s+5-p+1-c+287464-r+101424819-x+-n+6-ri+-ni+0-t+-k+
