for studs I would go generic. IMO you pay a premium when you want a particular design executed exactly the way its supposed to be by the original design house
I wore my 4-prong set, good specs solitaire studs to Cartier and my SA thought it was from them! Agree that although brand is not as crucial as the diamond quality, I would still prefer Cartier over Tiffany. JMHO.
i'd like to matfch if were you.. but i cant tell if cartier is better cause i dont own something from them YET.. so my advice would be go with what you love cause even if the quality is better or less you'll defently go with what you love
