Interesting... I know CIBJO's definition too... but their 'rules' are just guidelines, not mandatory.

Isn't there some debate still going on about this subject?

Can these roundish keshi [i] w/o traces of mantle tissue (an certainly w/o nuclei) even be identified as different from non-cultured? I used to think that it was only those traces of mantle that allowed a positive ID test.
