Having own 2 pairs of Mikimoto earrings, an Akoya in black pear earrings and a Mikimoto strand, I had purchased these earrings along with a bulk set of 5 white earrings for Christmas. I purchased these based on the review to give out for Christmas. I didn't give these out. I might give them to my nieces on their birthday. Again, I was disappointed at the size of the earrings. These were the same size as my pearl necklace with 5-5.5mm pearls. These are not definitely the 6mm size. I thought I was mistaken and went the the store to compare these with the 5.5-6mm in the jewelry cases. Yes, these Akoya earrings are definitely smaller than the 5.5-6mm in the store. The store also had 5mm and 5-5.5mm earrings. These black Overstock Akoya earrings were just that size--5-5.5mm.
Another thing is that these black pearls didn't look as good ad the white bulk ones I had ordered. The color wasn't peacock color, they look dyed--purple black in color. The workmanship was not bad. They look as good as my other black Akoya earrings, size 6-6.5mm. Those I got somewhere else. For the price of these earrings, I probably would not have paid this much had I known the color and appearance of the earrings were as such.
