That brooch is a Gabriel brand brooch, so it's understandable that both Emilie and Sabrina would have one:

Sabrina was gifted hers by Chloe, and Chloe - being the fashionable person that she believes she is - would only buy the best of the best jewellery pieces.

Emilie probably got hers as a gift from Gabriel, or maybe she was wearing it to show it off.

It's been confirmed they aren't exactly the same brooch, they are just the same design.
