I pass by this place, everyday when I bring my son to his Chinese tutor, that conducts seminar on setting up a pawnshop business. The Gemologist is actually the mom of two girls who I used to tutor.
I have no idea how to distinguish a fake jewelry from a real one so I'm really interested to enroll in this seminar. My tutees once told me that the students who enroll gets to learn interesting things about precious stones. They also advice what stores are reputable online.
One of these days, I will be one of the students in that class.
