IGI Certified Blue Diamond refers to a blue-colored diamond that has been graded and certified by the International Gemological Institute (IGI). The IGI is a well-known and respected gemological laboratory that provides independent assessments of gemstones, including diamonds, based on their cut, color, clarity, and carat weight.
When a diamond is certified by the IGI, it means that the stone has undergone a thorough examination and grading process by their team of gemologists. The certification report typically includes important details about the diamond’s characteristics, such as its color intensity, clarity grade, cut quality, and carat weight.
