Diamond Lab Report News
Accurate diamond grading plays a central role in many aspects of diamond and diamond jewelry retailing. To ensure that a retail jeweler maintains a high level of integrity within the company’s local marketplace, it is essential that diamond grading be fair and accurate. Misrepresentation of diamond quality is a surefire way for a jeweler to lose the trust of its clientele and perhaps land itself in legal difficulties. Fortunately, a number of highly qualified independent diamond grading facilities have been established over the years to help ensure that jewelers are accurate in their grading. The first modern grading system was developed by Richard T. Liddicoat of the Gemmological Institute of America. The system created by Liddicoat established the famous 4Cs for judging diamond quality that are so well known today. These criteria map a diamonds quality according to its size (caratage), color, clarity and cut. Color is judged on a scale ranging from the most desirable, or total lack of color, which receives the grade of D. Liddicoat explained that he started at D to avoid the mental connection most people have with grades beginning with the letter A, as used in academics. He wanted something independent. Clarity grades range from total lack of inclusions, or internally flawless, to eye-visible inclusions. A diamonds cut is determined by the proportions of its facets and facet angling, which combine to play the most important role in how well a particular stone refracts and reflects light to create brilliance and scintillation. Other important diamond grading labs established to serve the marketplace include the International Gemological Institute and the Belgium-based HRD lab. Each of these labs provide services to the fine jewelry industry including diamond grading reports, which codify a stone’s qualities for easy use by jewelers and consumers. While labs frequently remind users that reports are not guarantees of quality, they indeed are viewed by many as significant third-party documentation of a stones grades.
