Synthetic sapphires are lab-created either by flame fusion method or flux-melt method or less commonly, by hydrothermal method. They have the same physical, optical and chemical properties as natural sapphires. Some lab-created sapphires may be included, although most are clean. Since they have the same properties as naturals, they will not scratch or chip more easily than a natural stone.
