Having studied the Diamond Diploma, I am far more confident when buying diamonds to use in my designs. Being introduced to rough diamonds has definitely influenced my work. The course notes and instruments are excellent and the depth of knowledge of the tutors combined with their enthusiasm for the subject is inspiring. ODL allowed me the flexibility to study around my work whilst having the reassurance that my tutor was there to answer any questions and support me throughout the course.
