I have never seen high-level mikimotos in person. I have seen some of their lower-end pearls at a local Zales store (i think), and was pretty impressed with the quality, especially compared to other local stuff i've seen. However, the prices they list on their web site seem pretty extreme. simple A+ 6.5-7mm stud earrings are $300!!

are their pearls really worth the mind-numbing prices? or are you paying for the name as much as the pearl?
