Gemstones Identification reports can be divided in the
following different categories
- Brief Reports - This is usually the least priced sort of report/certificate available. These will provide you with the fundamentals of the stone examined, such as the stone type, weight, size, shape, clarity, and colour. There may be a comment area as well. The treatments the stone has had are unlikely to be included in the short report. However, they will almost always include heating/treatments for sapphires and rubies. The report will be packaged in a plastic cover the size of a credit card.
- Brief Report with Photo - These will have all of the information from the basic brief report, as well as an image of the stone being verified on the report itself, rather than on a separate sheet.Some laboratories that produce these studies are EMIL of Japan and AIGS. They do have certain limitations on the stones they will test. They don't test quartz variations very often.
3. Standard Reports - These reports are packaged in a sealed card / envelope with the gemstone inside. On the reverse, there is a plastic cover that allows you to see the stone. These reports include the following information: kind of stone, weight, cut, size/measurements, colour, and a comment area. Sapphire and ruby treatments are often indicated in the remark section.
4. Full Gemstone Report - This report is in card form, printed on original paper, laminated for preservation, and includes the gemologist's signature. This report will include the following information: the kind of stone, description, size, shape, weight, colour, clarity, proportion, finish grade, refractive index, specific gravity, variety & trade name, any treatments, and a photo of the gemstone.
5. Origin Certificate: On request and under favourable conditions, certain laboratories will additionally provide their judgement on the gemstone's geographic origin.
Note: Some laboratories accept all sorts of stones, whereas others, such as Quartz or Pearl, have limits.
