That is really interesting, I wonder if it's something like this: http://www.lightmachinery.com/Fluid-Jet-Polishing.html

"WTOCD originally acquired the patents of the GIP technology in 2008 and has since gone through a long and arduous process of putting it to the test. As noted above, the GIP technology allows for diamonds that cannot be polished against the grain – and therefore cannot be exploited commercially – to be put on the scaife and polished successfully."

"This result, of course, leaves our readers wondering what this technology entails exactly. However, at this point in time, no more information has been made public."

If patents in fact exist, that means that public disclosure of the GIP technology exists. Or, no patents exist and the technology is protected by trade secret.

I am aware of SiOx lapping of diamond off the running grain that was developed by RCA to manufacture phonograph needles from diamond. That involves quite a bit of expensive electronic equipment.

Found this patent, but that technology is nothing new and actually, is obvious:

Hmm very interesting indeed.. tho im skeptical atleast.. how it works out in a classic setup i.e Tang/dop and Scaif and result in finnish and speed , cause u can pretty much do this allready with a diamond impregnated scaif though slow and not have a smooth finnish on the stone..

I am skeptical as well:
One article mentions a cutting temperature of 35 degrees Celsius. Any such temperature would be the function of pressure and speed. So they get a chemical reaction between close-packed cubic carbon and something else that occurs just below body temperature?
Also mentioned are patents from 2008. So after more than 5 years, this alleged technology still has not been developed for general use? If such patents really exist, how valid are patents that cannot be used in production?
And finally. Show us the patents!
