What Is a Triangle (Trillion) Moissanite?

• Three equal sides (equilateral triangle)
• Sharp or slightly curved edges
• Brilliant-style faceting
• Exceptional light dispersion

The trillion cut is known for its dramatic presence and modern appeal. It is commonly used as a center stone or side accent in engagement rings.
