Documentation
The results of the examination are compiled into a GIA Diamond Grading Report or Dossier, which includes detailed information on the diamond’s 4Cs (Color, Clarity, Cut, Carat Weight) and a plotted diagram of its clarity characteristics. At Callista Diamonds Co., our commitment to quality and transparency ensures that every diamond you purchase is of the highest standard.
