Sorry, I have not been following the whole Queen Mary Cartier Lozenge tiara story. But the fact that it is kept in a new cardbord box with bubble wrap somehow raises a big red flag with me.

There is something with this that - to me - screams copy made by a (local) goldsmith. I am not trying to say that the tiara cannot be made in gold/silver and with real diamonds… but somehow I think from this photo that something is off…
