Hi msop! No offence taken, thanks for the post.
For me personally, there are a few reasons why I'm sticking with Tiffany here:
1. The diamond is an upgrade for me. Although I did consider looking elsewhere and keeping my existing Tiffany diamond, the trade in policy is valuable and the amount I will have to pay over and above is less than what I would have to pay for a non Tiffany for the same size I'm looking for. It could be a different story if this was my first ring...
2. Although I'm willing to trade in my existing diamond, there is some sentimental value in sticking with the same classic Tiffany ring chosen by my husband way back when. At that time, I did not have any input into the ring and he chose it on his own (all he knew was that I wanted a simple round brilliant platinum setting). I want the same style he originally chose for me, just bigger =)
3. I think the classic Tiffany setting is really pretty. I've seen other simple 6 prong classic settings which show the culet/full diamond more etc but something about the Tiffany classic setting "sings to me". I love it.
Those are my reasons off the top of my head. I wouldn't choose a ring based on service per se, but my experience has been great. The inventory is lacking in what I'm looking for, but the SA's have been helpful.
For now I've decided I want certain angles, percentages, depths etc and will wait for the right stone. If I'm going to pay Tiffany prices I may as well get what I want (or atleast close!)...although at this rate it may take a year or perhaps never happen? =(
Thanks for the good luck, I hope I find it too!!
