Distance/Online Training on Jewelry

Hi All , It seems no one had the solution for my problem !!

Hanuman, could you pls. help me finding basic Costume/Artificial
Jewelry casting tutorials ? Or offering any suggestions on the
subject ??

Is there any Institution willing or exists anywhere is the world
…offering Distance/Online Education courses or Affiliations on fixed
terms & conditions??

e.g. As a NGO I am planning to open one “Center For The Development
Of Gems & Jewellery” which would be basically for the teaching Gem
Faceting and Jewelry skills to the persons living below poverty line
(for Self-employment) in the society?

Thanks for your time reading all this…
