*** Warning long post. 
Please help me deicide which earrings I should get. I've been thinking about purchasing Princess Cut Studs... please give some input as I do not know much about White Gold vs Platinum and how big of a difference it actually makes and whether its worth the price difference.
Just a bit of background... I'm in my early to mid 20s. I went to Costco today and an employee was kind enough to show me 2 pairs: 1ctw (1/2 carat each) set in 14k White gold $2,200 and a smaller .5ctw (1/4 carat each) set in 14k white gold also $600. It didn't say anything about color and clarity. the .5ctw looked great but when I tried the 1ctw... it looked a great deal better, but that price is a bit steep and I would need to wait until I get my first "real" job before I could afford that. Even the man helping me commented that the 1ctw was a WOW while the .5 was great until you saw the larger pair. I'm looking for a pair that I would be able to wear on a daily basis. I also live in a big crowded city so another thing to think about is how safe it would be to wear larger sized earrings. So... I'm looking on blue nile now..... and here are the options:
Platinum set (Diamond is G-H color and at least VS clarity) :
- 1/4 ctw $325
- 1/3 ctw $425
- 1/3 ctw $725
18k White Gold set (Diamond is H-I colo and at least SI clarity):
- 1/4 ctw $200
- 1/3 ctw $275
- 1/2 cwt $600
The smallest size I've seen in person is 1/2 ctw (and that size looked acceptable to me) so I do not know how small the other sizes will be.
So my question is... what size is best and what setting? How much better will the platinum look and is it worth the extra money? Thanks so much!! Any advice, extra information, personal experiences, or input will be greatly appreciated!
