Bean. The popularity of an item isn't a great endorsement, but it's not to the piece's discredit, either.
In my mind there's a binary distinction between the pieces you're deciding between. VCA has cultivated a slighter and more prestigious brand presence than Tiffany, while Elsa Peretti represents the ********ization of fine jewelry and a modern way of wearing and engaging with precious materials.
Imagine you wear the same shoes as someone else to a formal event. Would you feel like your outfit was cheapened? If so, grab the sweet. Would you compliment the other person, maybe have a laugh, and still feel confident in your style? Get the bean.
