This item can help you identify your mystery gemstone.
Gem Dialogue is an industry standard for gemologists, dealers, appraisers and retail jewelers to accurately describe, record and communicate gemstone colors. Use the included 21 transparent color charts that show 10 different saturation levels of basic colors. Includes 3 masks, used to show how much color is hidden by black or brown. By mixing the charts, you can accurately describe more than 60,000 colors! Keep detailed records of customer purchases and provide precise color descriptions in appraisals. Includes a CD explanation of Gem Dialogue and a detailed instruction and grading manual. Also included is the Gem Dialogue Toolbox, a cross reference to the color descriptions of other systems.
