Where in Jaipur can I find a factory that cuts and polishes semi-precious stones?

Answer 1

Do you want to buy the stones, or do you find a job there, or you want to sell uncut stones?
There are lots of businesses which specilise in all three or just one of the three. Some of the businesses will hire you as an apprentice to work and learn.
Buying and selling is easy, for working in one of these businesses you would need references.
