  • Settings: Prong, bezel, pave, and tension for style and security
  • Certification: GIA or IGI certified diamonds to guarantee quality and authenticity

Expert Tip:
Prioritize the diamond’s cut to maximize sparkle and brilliance, especially for larger stones. Consider protective settings such as bezels or halos to safeguard your investment.
