New pearl book will be released on sep 15, 2025

I met Renée in Tucson in 2011 shortly after her 2010 update to the Buying Guide, which included a contribution or two of ours. She updated it again in 2017. Eight more years of research should be worth waiting for! I wonder how up to date it will be on the nacreous/non-nacreous conversation. In Chapter 8 it appears she addresses this specifically.
 
Interesting-- I didn't know that.
In reference to the crisis starting circa Y2K when the labs suddenly began being inundated with pearls for natural certification. Micro CT scanning protocols were developed by 2010 to detect tissue nucleation in un-drilled saltwater pearls, staunching the fraud. But the keshis are nice!
