The '4Cs' are an international appraisal criteria for diamonds prescribed by the GIA (Gemological Institute of America).
TASAKI sends its graders for diamond appraisal and discernment courses at the GIA. Based on the criteria learned there,
we set even more stringent in-house standards to ensure that our professionals preserve the TASAKI diamond quality.
