MM should not have been presented with controversial jewellery. She would have been presented with a tray of earrings (most likely designated to her), but she would not have necessarily asked too many questions, because the controversial ones should not have been included.
If you read the Royal Family guidelines that I quoted from upthread, the earrings were not controversial when they were given to the Queen as a wedding gift for Meghan. And, as they were a wedding gift to Meghan, they then formed part of Meghan’s collection and were under her own control to use as she wished (though they were not her personal property, so she could not sell them, for example).
I’m sure Angela Kelly would be interested in your suggestions for how things out to be run, though - why don’t you write to her? 😄
I actually think it’s reasonable to think that Meghan may not have joined the dots and realised they were now suddenly a controversial gift once she’d already selected them to wear on the tour. Unhelpfully though, the fact that their provenance was concealed suggests that this was quite clearly not a genuine mistake - somebody knew!
Sam Cohen told the press that the earrings were borrowed, which was not true (not even from the Queen, as explained above - they were in Meghan’s own control) and that they were also borrowed from Chopard - also not true (they were in actual fact made by a firm called Butani).
It would be interesting to know if Sam Cohen was lying to the press when she said this (Meghan was pretty adamant when talking to Oprah that her team weren’t prepared to lie to the press to protect her, though) or someone had in fact misled Sam Cohen herself (a very senior employee), knowing that what she told the press wasn’t true.
