Perfect Pearl doesn't know what he's talking about and was getting on my nerves. A gemologist can't prove a pearl is marine or freshwater unless they have equipment that costs thousands of dollars. Perfect Pearl got his diploma from a correspondence course where overseas students are excused from the practical gemstone identification test.

Honestly, most gemologists don't have enough experience with pearls to tell you much about them. That is why GIA created a separate pearls course, including a lab where you could see and handle the different kinds of pearls. If identification is important, it's best to take it to a lab that has experience with pearl identification.
