Moissanite in the jewelry industry is entirely synthetic material — and for good reason. With one of the highest refractive indexes and light dispersion ratings of any gemstone simulant, moissanite produces an exceptional display of brilliance and fire that rivals diamond. For jewelers seeking a premium diamond alternative for customer settings, moissanite is the leading choice in the industry.

This round moissanite measures 6.5mm and is sold by the piece, making it easy to order exactly what you need for individual commissions or small production runs. With D–E colorless grading and VVS clarity, this stone is suitable for fine jewelry applications and high-end custom work.

Features

  • Exceptional brilliance and fire from high refractive index and light dispersion
  • Colorless D–E color grade — visually comparable to top-grade diamonds
  • VVS (Very Very Slightly Included) clarity for a clean, bright appearance
  • Machine cut for consistent faceting and symmetry
  • Compatible with cast-in-place setting techniques
  • Suitable for all standard jewelry cleaning methods
  • Mohs hardness of 9.25–9.5 for excellent durability in everyday wear
  • Tight manufacturing tolerance of ±0.08mm ensures reliable fit in calibrated settings
