Nope, it is still there.

Jeremy, please tell us about the inevitable (and possibly suicidal) politics that would result from your—and other on-line pearl dealers—simply going your own way? I realize you do a bit of that already.
Well, for the most part my disagreements with CIBJO are the same disagreements others in the industry will have. To me much of it is academia taking its own approach and asking the industry to follow its lead. This does not make sense as the academic side of the industry exists because of, and in order to serve the industry. In that sense I feel safe enough to continue with my current terminology usage.

The GIA is quick to accept the terminology proposed by the confederation, as an academic authority. But the powers that be at the GIA do not understand the pearl industry, or the science of pearls (for the most part).

Other misgivings I have about the terminology are that there are too many mistakes. Page 16 was a case in point. Only one of my assertions can be debated - the use of the term keshi. The others, even the tongue in cheek reference to human invitation instead of human intervention, are real mistakes.

A single member of CIBJO (H.A. Hanni) was responsible for the omission of terms such asnucleation, nucleus, bead-nucleated, and tissue-nucleated. As he put it, for the sake of clarity we are now to use only the terms beaded cultured pearl and non-beaded cultured pearl.

His basis of reasoning is that the terms bead nucleated and tissue nucleated are confusing as bead nucleation always is a combination of bead and tissue. Furthermore, tissue nucleation does not mean that the tissue remains in the pearl - it is not a nucleus.

The above reasoning is not completely correct in my opinion. In second generation production a tissue piece is not used in bead-nucleated pearls. Also, there are several thing that can happen in tissue nucleation, one is the tissue becoming the nucleus.

My biggest problem with these changes is the fact that they were proposed and accepted to alleviate confusion. In fact, they create the confusion.
