A grading report is a document that verifies a gemstone’s identity, describes its grade results, and discloses treatments and characteristics. It typically lists the gem’s identity confirmation, carat weight, measurements, color grade, clarity grade, and cut or finish, along with any treatments (such as heating, fracture filling, or irradiation) and other notable characteristics or origin information recorded by the lab. This kind of report gives buyers, sellers, and insurers a transparent basis for understanding value, authenticity, and potential holds or limitations of the stone. A warranty is a guarantee about performance or durability, not the gem’s grade or treatments. A certificate of origin focuses on where the gem came from, not its grade or treatment disclosures. A price quote is simply an estimated price for purchase, not a grading assessment. So the grading report best describes a document that verifies identity, describes grade results, and discloses treatments and characteristics.
