Joanna Hardy Courses

Hi!  I am a lover of precious gemstones and interested in taking the Joanna Hardy courses.  In the ruby and emerald sections, there is reference to Mozambique rubies and Zambia emerald, respectively.  Will there be discussions and comparison of those stones to Burma rubies and Colombian emeralds?   Thank you.
