Color in diamonds arises from defects or impurities such as nitrogen, boron or a lattice vacancy. Therefore, suitable types and quantities of defects will assist in creating the most desirable color in a diamond. In this research, ESR spectroscopy was used to find the optimal annealing temperature f...
