| Hi Sam,
Yes I have seen these before. They are probably the world's greatest waste of money and were grown in Korea and China on commission for Japanese factories. Up until the early 1970s such small pearls that typically found their use in end pearls of graduated strands and accents in rings and brooches were typically keshis without nucleus. However when culturing times went down drastically, the keshis were too small to use for that and the factories commissioned the lowest-wage countries available to nucleate micropearls.
