The Diamond Dossier is not issued for synthetics, simulants, mounted diamonds, diamonds that have undergone unstable treatments such as fracture filling or coating, or diamonds that have been HPHT processed. Any evidence of other treatment is prominently disclosed in the report.  \n11. FLUORESCENCE  \nStrength and color of the diamond when viewed under long-wave ultraviolet light. A fluorescence description of “none”represents a range of fluorescence from Indiscernible to  \nVery Faint. Used for identification purposes.  \n12. CLARITY  \nCHARACTERISTICS  \nList of the most significant clarity characteristics present in the diamond that justifies the clarity grade; a maximum of four characteristics are listed.  \n13. INSCRIPTION ( S)  \nAny text, symbols, logos, or a unique GIA report number inscribed on the diamond’s girdle.  \n14. COMMENTS  \nAdditional identifying characteristics or features that are not otherwise represented  \non the report. If a treatment is detected, such as laser drilling, it would be described here.  \n15. PROPORTION DIAGRAM  \nGraphic profile representation of the diamond’s actual proportions.  \n16. GIA COLOR SCALE  \nIllustrates the GIA Color grades and their relative positions in the GIA Diamond Color Grading System.  \n17. GIA CLARITY SCALE  \nIllustrates the GIA Clarity grades and their relative positions in the GIA Diamond Clarity Grading System.  \n18. GIA CUT SCALE  \nIllustrates the GIA Cut grades and their relative position in the GIA Diamond Cut Grading System. Available for standard round brilliant cut diamonds in the D-to-Z color range and Flawless-to-I3 clarity range.  \n19. SECURITY FEATURES  \nMicroprinting, security screens, watermarks, a two-dimensional barcode, a hologram, and sheet numbering safeguard report integrity and facilitate document authentication.  \n20. QR CODE  \nA two-dimensional barcode that, when scanned, verifies data on the report against the GIA database.  \nTREATMENTS  \nSome diamonds are treated to improve their color and/or apparent clarity to increase the value. All GIA diamond grading reports will disclose the presence of detected treatments. Both color and clarity treatments are disclosed on reports under the Comments section. Additionally, color treatments are indicated with a * next to the color grade. GIA does not issue reports for any unstable treatments, like coating or fracture filling.  \nColor treatment examples:  \nCoating: masking the diamond’s natural color with an ultra-thin layer of chemicals or plastics. Since this treatment is considered unstable, GIA does not issue reports for diamonds where coating is detected.  \nHPHT (high-pressure, high-temperature): heating a diamond to high temperatures under high confining pressures to remove or change its color.  \nClarity treatment examples:  \nLaser drilling: using a laser to bore a small hole into the diamond’s interior to burn away the inclusion, or create a channel through which a bleaching agent can be introduced to improve the inclusion’s appearance. Usually used for small dark inclusions.  \nFracture filling: injecting a glass-like substance into the fracture to improve the stone’s apparent clarity. Since this treatment is considered unstable, GIA does not issue reports for fracture-filled diamonds.  \nSYNTHETICS  \nA synthetic diamond is the result of a technological process, rather than the geological process that creates natural diamonds. Synthetic diamonds are made and have essentially the same chemical composition, crystal structure, and optical and physical properties asa natural diamond. Since synthetic diamonds are virtually identical to natural diamonds, differences only become clear when they are viewed by a trained grader. GIA issues synthetic diamond grading reports which look distinctly different than diamond grading reports issued for natural diamonds.  \nSIMULANTS  \nSimulants ","cbCaiberzLMhDt4b","https://ap.wps.com/l/cbCaiberzLMhDt4b","pdf",3661463,"English","# Anatomy of a\n## 4Cs assessment and report number inscription\n# Guide to Understanding GIA Diamond Grading Reports\n## Date\n## Report number\n## Shape and cutting style\n## Measurements\n## Carat weight\n## Color grade\n## Clarity grade\n## Cut grade\n## Fluorescence\n## Clarity characteristics\n## Inscription\n## Comments\n## Proportion diagram\n## GIA color scale\n## GIA clarity scale\n## GIA cut scale\n## Security features\n## QR code\n# Treatments\n## Color and clarity treatments disclosed\n## Coating and HPHT\n## Laser drilling and fracture filling\n# Synthetics and simulants","[{\"question\":\"What is the Diamond Dossier used for and what diamonds qualify?\",\"answer\":\"It is used for loose natural diamonds between 0.15 and 1.99 carats in the D-to-Z color range.
