Please help authenticate Cartier mini love ring

[manichaeism]

I bought this from a Japanese eBay seller with great reviews, but I’m concerned because there is space after Au and this doesn’t look like my real Cartier bracelet (but my bracelet is rose gold and brand new and very shiny). Please help!

It’s difficult to authenticate Cartier pieces as there are some excellent fakes being made.
That aside, FYI it is actually a criminal offence to sell or trade in replica goods in Japan so buying designer articles from Japan is usually safe.
Also the business sellers in Japan on eBay have to be licensed.
