6. Certification

Diamond grading reports are issued by independent gemological laboratories. While there are several grading laboratories, Washington Diamond sells diamonds that are graded only by the Gemological Institute of America (GIA - GIA.edu).

It is our opinion that GIA has the most accurate and valuable standards that ensure proper quality in a diamond. A grading report recognizes quality characteristics identified in a uniform laboratory environment, which allows you to gauge and compare quality and value.
