What Our Students Say
Georgina Callanan | Past Student
For as long as I can remember I have had an interest in gemstones. This fascinating course takes you through the geological formation of gemstones, identifying gemstone properties and most of all, hands on practical experience with gemmological equipment and specimens. This course helped me get back to learning something exciting and new and made learning fun again. It impressed me so much that I am currently pursuing a career in gemmology. Most of all, what made the course experience all the more worthwhile was the care and dedication shown by the course lecturers ensuring that everyone was learning together and that the course was enjoyable for all.
