I don't know Bulgari (Bvlgari) well enough to know whether that listing or any of her other listings are authentic or not. (I do know
Coach but she doesn't show some of the necessary pictures needed to prove or disprove authenticity of the bag.)
What I will say is that your concern with the lack of "authenticity cards" is, IMO, baseless. Props get lost, discarded as well as faked. Or genuine props can be used in listings of fakes to "prove" authenticity of a fake.
It's not the props that prove or disprove authenticity. It's the details of the items themselves and if the right pictures are shown and can prove authenticity of the items, that's the important thing.
No item should ever be reported unless you know what makes it fake and lack of authenticity cards proves nothing. (And in fact, some brands don't have "authenticity cards" and if listings of those brands show them, it's a red flag.)
