Gemscite’s practical gemology courses offer real-world exposure to gemstone testing and grading. Instead of learning only from textbooks, students handle actual gemstones and work with real lab tools like refractometers, polariscopes, UV lamps, and microscopes. Our classes are small and interactive, ensuring one-on-one guidance from expert instructors. You'll learn how to distinguish between natural and synthetic gems, identify treatments, and grade diamonds and colored stones. Perfect for students, retailers, and anyone entering the gem trade. With hands-on training, your skills become immediately useful in the field — not just on paper.
