You guys are really cracking me up! ..class of 90---good grief! (Note to self: do not drink coffee while reading this post!) Pattye, there was no pearl stringing/ knotting instruction as part of the hands-on lab when I attended. I actually expected it, but it wasn't part of the course. In fact, I would have really appreciated a detailed chapter on jewelry manufacturing/construction with pearls. Toward the end there was some discussion with respect to design with different types of jewelry. Also, BTW, my lab instructor mentioned that GIA may include pearl instruction as part of their gemologist program, but I haven't heard any updates.
