Hi Jean Marie,
regarding HPHT most common system (russian split sphere) i think almost all manufacturers started from Russian systems. InThis interesting article from Marty Haske on his Raman spectrometer there are some stones provided by Chatham claimed as old Kiev production. I don't know if actually Chatham produces synthetics in USA, what is clear is that some years ago they made stones in Kiev and, regarding Italy, there is, right now a local synthetic manufacturer who estabilished a factory in russia and sells synthetics here.
ciao
alberto
