This is my first post on the forum. I have learned a lot by reading previous posts already and thank those who are contibutors.

I recently purchased some loose undrilled chinese fw baroque pearls I have sorted out the overtone and orient features thanks to the wonderful post on this topic. My question is what is it about the culturing process that gives the majority if these pearls a flat back? Some only have a small spot that is flat but out of over a thousand or so pearls only a very few do not have a flat back.

Full round eight way rollers you can have them , give me the character of some nice baroque pearls.
