• Color-Sure



  • According to rules, the color evaluation must be performed on the basis of visual comparison.
  • Nonetheless, a test performed through a colorimeter such as Color Sure makes the gemologist more confident.
  • This tool, especially built for a gemological use, is really trustworthy: half error grade, either rife or failing.
  • A wide spectrum light bundle crosses the examined diamond; the absorption values, gained through a spectrometer are developed through a complex software algorithm which gives back Color Sure on a D - Z scale.
