Additionally, a genuine diamond will have unique characteristics under magnification, such as inclusions and facets, that synthetic or imitation stones may lack. Consulting with a professional gemologist or jeweler can provide a definitive answer regarding the authenticity of a diamond. **

Finally, diamonds have a higher refractive index, which gives them a greater brilliance and sparkle compared to cubic zirconia. **
