Gübelin is developing block chain to be able to track rough with mine area and after cut this is so nice for the public to know origin
This is an exciting development. It would be nice to have a machine that can let you know if something is natural or synthetic. I’m sure it will require updates as the synthetics improve to avoid detection by this machine. The AI may even be able to discover other ways of determining the authenticity of gemstones and their origins the same way AI has been able to detect cancer in ways human pathologists didn’t know was possible.
