I have a very limited budget, around $2500, but my girlfriend is set on a platinum setting, she DOES NOT want white gold. She loves the tiffany classic solitaire setting and I do too. I am not opposed to getting a replica, if it is a good one, but the best replicas in platinum are around $1200 dollars (I like the superbcert) which leaves me $1200-$1300 left for the diamond. We know we are going to end up with a small stone, especially because we want it to be good quality, G or H color, SI1 or better clarity, excellent cut. I called tiffany''s, and they said I can get a ring with a diamond between .25 and .32 carats with this budget. My question is, am I really going to be able to get a much better/bigger diamond if I set it in the superbcert replica or is there a good, less expensive one out there? My impression is that the tiffany''s markup is less with a lower budget and that way I end up with the exact setting I want. Any advice would be great, thanks.
