What Will I Learn?

  Learn how to tell the difference between natural and synthetic gems. This course takes an in-depth look at the treatments and synthetic gems.

Self study at home, briefing, practical and exam on campus.
With a collection of over a thousand rough and cut stones, this course offers students a rare opportunity to examine all the major synthetic and treated gem varieties found within the marketplace.
Being able to identify synthetic and,  especially, treated materials is a vital aspect of the modern gem and jewelry industry and many gem dealers have lost large sums of money by buying such stones as natural.
