Question about Kasumiga pearls

[JWei]

Generally the kasumiga pearls have nuclei. Could anyone explain where these nuclei are inserted (pearl sac or gonad)? Are there any tissue-nucleated Kasumiga in Japan? I have seen some tissue-nucleated pearls in China, which seem to be similar to Kasumiga, but have broken outlayer.

Do contact Sarah, as barbie biggs indicates. She is very knowledgeable and interested in pearl education. See this LINK on the Kojima Pearl website for a basic description of many pearl varieties, including Kasumis.
