QUESTIONS & ANSWERS ABOUT GEMDIALOGUE
WHAT IS GEMDIALOGUE AND WHAT DOES IT DO?
GemDialogue was engineered for the gem trade to supply portable, uniform color reference points in an affordable product. It offers you a practical way to communicate with others in the gem trade, when talking about gemstone colors. For many years we have had a good communication system for colorless diamonds, but none for color gems or fancy color diamonds.
HOW DOES IT DO IT?
THE SYSTEM COMES WITH THE FOLLOWING:
A HIGHLY PORTABLE COLOR CHART MANUAL (in loose-leaf form, 9-1/8 X 4-1/2") containing 21 basic transparent color charts showing ten different saturation levels for each color. Each chart was prepared to represent a basic color area of the GemDialogue color circle. The circle was designed to provide a color sequence environment into which virtually any gem color will fit. It does this using 20 basic color areas further subdivided into 44 color spaces. On each chart the colors are shown as pure colors from strong to weak (without black or brown). Black and/or brown tints in a gemstone may be simulated with transparent "color mask." A black to gray mask and a brown to light brown mask, also showing 10 different levels from light to dark, are also included. These may be placed over the chosen color to show how much color is hidden by black or brown. An opaque black to gray mask is also included to be used when describing opaque materials, by placing this mask behind the color chart.
A FIVE SECTION INSTRUCTION AND GEMSTONE GRADING MANUAL, IN LOOSE-LEAF FORM:
SECTION ONE; holds the basic instructions for using the system. It explains the system concept, in plain language, and supplies a worksheet form. This form covers the color descriptive factors and other factors which serve to give a complete description of the stone. This section also gives complete definitions for each of the worksheet factors to ease the learning process.
SECTION TWO; contains instructions for mixing the color charts, allowing you to achieve over 60,000 colors to match against. No need to memorize color mixing because a color spreadsheet is included in the appendix.
SECTION THREE: is a 65 page grading manual on applying the GemDialogue color system as a grading tool. This section will help you understand the subjectivity involved in grading and pricing gemstones and can be integrated into your own grading protocol.
SECTION FOUR; suggests ways to use the color comparison options of this system to overcome the guesswork involved in using only the verbal terms for fancy color diamonds. You are now able to use the verbal description together with an actual color reference.
SECTION FIVE; is an appendix with the forms and charts needed for efficient use of GemDialogue. It also discusses the ideal lighting source.
PLEASE NOTE that this manual is based on personal experiences and that other dealers' subjective judgments must also be considered. If you use this as an introduction to grading and make your own notes about your experiences with other dealers, you will be well on your way to understanding the gem grading process.

- A TWELVE MINUTE VIDEO is also included which shows the ease of the gemstone color matching process.
- THE GEMDIALOGUE COLOR TOOLBOX is also included. It has over 2,000 cross-referenced color notations and terms allowing you to talk color with people who have other color systems which have been used in our industry. The authors Gail Brett Levine and Howard Rubin spent over two years physically matching GemDialogue colors against those of the other systems. This book is the printed edition of our color system terminology database.
HOW CAN YOU PUT IT TO GOOD USE?
If you are a jeweler you can now keep meaningful colored stone inventory records for insurance purposes, just as you do for diamonds. You can keep an accurate customer color record for matching to your buying and making suggestions for follow up sales. You can also talk with dealers having the same system and order without sending samples through the mail.
If you are a dealer or a manufacturer you can keep notes of the qualities and colors your customers use instead of tying up actual sample stones. Manufacturers can designate color ranges for your quality control and pricing. You can carry the system with you on buying trips so that your suppliers can see what you have in mind. No computer needed. You are carrying 60,000 colors in you briefcase.
If you are an appraiser you will find that your previous appraisals will now provide a color research record which you may reference for new jobs. Your GemDialogue reference points will aid your color recollection as opposed to just verbal color descriptions. Previous "comparables" will be easily accessed and save research time.
If you are a gemologist you can designate where a ruby color ends and pink sapphire begins. There is a very fine dividing line between a pink sapphire and a ruby, as well as between an emerald and green beryl. Country of origin colors may be clarified by showing the particular colors expected from a given area. Fancy color diamonds also need reference points for proper color description, and GemDialogue can provide that need.
