Your pieces are beautiful. Love them all!
Regarding their CS- I've had one issue that did make me feel uncomfortable until I called her out and she apologized.
Last year, my hubby bought me an 18 inch chain to go with my lock that came with a 16 inch chain.
I noticed right away that the color (pink gold) was much more pink than the lock or the chain it came with.
I went to my local Tiffs (on Wall st in nyc), and explained how I wanted to exchange the chain my hubs got there due to the color difference.
At first, the CS who helped me kept saying how she couldn't believe how much pinker it was than their other chains. She kept going on and on. Eventually, it started to feel as if she was insinuating that the chain I'm exchanging is not theirs. Like I'm trying to pull something over on Tiffs.
I had enough and finally said "what are you trying to say? that this isn't your chain??" She looked at me wide eyed, realized how she sounded, and started apologizing over and over.
It became very uncomfortable. I picked out the closest match, exchanged and left as quickly as possible while she was still apologizing.
I went back for the first time after that incident only a few weeks ago. So glad I didn't see her..lol..
