Hi, I've been allowed to try the real once both times I visited Cartier in US. First time in Chicago for 2 years ago, no problem, first they sized me with the love sizer, then I tried the real one in rose gold and did not buy (as I know now, it was stupid as the currency exchange rate was favourable then and price was lower...). Then I tried it again here in Boston for 2 weeks ago, also without any relationship with any particular SA. And it was a queue in Cartier in Boston. I've never seen a queue in a luxury jewellery store... Anyway, I've tried the real one and bought it
Now contemplating on buying the white gold one.
I've also tried it once in Berlin, the same, the real one was mounted on my wrist promptly. I didn't buy it, but it bought the Love ear rings in rose gold.
It's very strange that some SA do not allow customers to try the real ones. While I had the sizer on me, I really hesitated, but once the real one was mounted, I was completely sold....
So it's in the interest of the business to let the customers to try the real ones.
