Yeah, take a break. It's not happening for a while, so I think it's best if you stop looking and stressing about it now but resume looking again a month before the purchase date, especially since diamond prices will fluctuate and what you find now may be gone/higher in price later. If you are set on spence, I won't dissuade you, but don't sacrifice quality or be swayed by the seduction of a perceived good warranty for carat size. The fact that spence does in house grading is a little alarming.
Agreed.
I think if you're set on tiffs then you won't be happy with anything else.
My bf just bought the soleste... I was also contemplating between getting a bigger diamond NOT from tiffs. But it's always been my dream to have a tiffany ring. So though I didn't get my desired carat size... 2 ct and over I love my ring! I'd post a pic but bf doesn't want me to post until we're officially engaged, otherwise I would love to share!!
