At Callista Diamonds Co., we pride ourselves on dealing with GIA certified diamonds. The Gemological Institute of America (GIA) is renowned for its rigorous grading standards and expertise. Our diamonds are meticulously evaluated by highly skilled graders in tightly controlled viewing and lighting environments, ensuring consistent and precise determination of each diamond's characteristics.
Color Grading:
Diamonds are compared to a master set under controlled lighting to determine their color grade.
Clarity Grading:
Using magnification, graders identify and evaluate inclusions and blemishes to assign a clarity grade.
Cut Grading:
The proportions, symmetry, and polish of the diamond are assessed to determine the cut grade, which influences the diamond's brilliance.
Carat Weight:
The diamond is weighed to the nearest hundredth of a carat.
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. Experience the brilliance and integrity of Callista Diamonds Co., where exceptional diamonds meet unparalleled expertise.
