What Is A Lab-Grown Diamond? Why Is It Pricier Than Moissanite?

  • Cultivated diamonds are real diamonds,
    which are grown in laboratories using advanced technology that mimics the environment in which natural diamonds are formed underground.
    It is identical to a mined diamond in composition, hardness, fire and brilliance.
  • Unlike moissanite or cubic zirconia, which are “diamond-like” materials that only look like diamonds,
    are not real diamonds and cannot be certified by professional gemological organizations such as the IGI or GIA. And we screen every single cultivated diamond in-house.
