  1. Dear Sir/Madam,

    Thank you very much for the Rough diamond grading and evaluation course, it has provided me very important knowledge and skills about rough diamond and its evaluation. Once I have registered for licence trading, I intend to register for the next course.
    However, my request to the team is to check whether it is possible to provide us with notes or recommended book or whatever educational material relevant to our first course so as to enable us to remind ourselves where its necessary.
