I FINALLY got my first pair of high end pearls. I wanted something for everyday so I chose 6mm Mikimoto studs. We got them from the only authorized Mikimoto seller in town, so I'm assuming they are the real deal. Are they supposed to come with some kind of grading report? We got the AAA, which is supposedly the best. The tag and receipt say AAA, but there is no authenticity card. I am new to pearl jewelry so I have no idea if they should come with some kind of card to prove their quality. Am I freaking out over nothing? They were pretty expensive.
