hi Sam
Hi Sam, I am a oversea jewelry sales, got a GIA grading.. tired of flying and want to change career..interesting in 鑽石切磨師, as I saw your reference describe you had a 鑽石切磨師..is it worth and useful to study a rough diamond course and diamond cutting course, n I don't see they have this kind of course in Hong Kong, where do u study? .Is it going to work to purchase myself some rough diamond and cut it my own after the course? any suggestion? want to change my career. thanks
