Hmm... I think it was 6-7 years ago. I had wanted the width size Small which was very hard to find at the time. I was in Vegas at Bellagio, and I bought it at the Tiffany boutique there.
I'll never forget that event as the SA first showed me the medium width and insisted it was the small width. I said, that is the "size" small (cuff diameter), but the width is medium. I told her I did not want the medium width as it made my wrist look too chunky.
Well, she went to the back and lo and behold, poof, a small width in size small shows up. I think she was just lazy to search, and I am glad I was persistent.
I love the Bone Cuff. I hope you get it.
If you go to Tiffany, try on the Bottle necklace while you are there. The bottle necklace is my second favorite Peretti piece. It looks fabulous when worn with the Bone Cuff... very sleek, yet it makes a statement.
Hope this helps. Good luck!
