Various methods or techniques are used to produce synthetic gemstones.

  • Flame fusion (Verneuil process produces mainly corundum and spinel)
  • Crystal Pulling (Czochralski process produces mainly Ruby & Alexandrite)
  • Skull Melting (Produces mainly Cubic Zirconium oxide)
  • Zone Melting (Process produces mainly corundum & Alexandrite)
