1st of all, thx for your reply.
I also want to ask another question, any different (other than price, i know there are big different!) between Pt and white gold? e.g. appearance, maintence...etc, thank you.
actually, my budget is below $15k, with ring. I know that it is impossible for D and E colour.
How about G-I, VS1-VS2, better with 3 EX H&A. Thank you.
