My C de Cartier necklace is about 0.9 ct. I don't get any flipping at all. I had the chain lengthened and the necklace can still slide around. It's all about the setting for me. The stone reads larger than it is.I'd been leaning toward CdC because of the unique setting, but now the concept of the stone flipping is bothering me. Is it really that noticeable? Who has one that's about .75-1ct of either the CdC or the 1895 that can comment on the wearability or post a modeling photo?
If you can, contact your nearest store prior to going in, so that they can bring in a choice of necklaces for you to look at. I don't think this one shows up online very often. When I bought mine, I had a choice of 2 or 3 that were close in size that had been brought in for me.
