Hello, does anyone know of an authentication service for Cartier Lanieres diamond earrings? There is no Cartier shop in my state. I took the earrings to a local jewelry shop that sells some preowned Cartier, and they said it looked good, but I would feel better with a second opinion. I saw that authenticate4u does Cartier watches, but they do not specify if they will also authenticate Cartier jewelry. Thank you.
