GemDialogue® takes pleasure in announcing a celebration of thirty years of continual service to the jewelry industry with its portable color memory system. Founded in 1982, GemDialogue® offers appraisers, dealers, jewelers and gemologists a repeatable and meaningful accurate color record for gemstones and colored diamonds.
Howard Rubin, GG, inventor and founder of GemDialogue®, spent ten years developing the color system before offering it to the trade. GemDialogue® was engineered for the gem trade to supply portable, uniform color reference points in an affordable product. It offers a practical way to communicate with others in the gem trade, when talking about gemstone colors.
The color communication system contains 21 basic transparent color charts showing ten different saturation levels for each color. A black to gray mask as well as a brown to light brown mask is also included. The charts and the color masks offer 60,000 color possibilities for matching.
GemDialogue® allows grading color gemstones from transparent, translucent to opaque materials. Challenging variants such as dichroic, poorly cut, or zoned material are easily color graded. Rare material such as Paraiba, Burma and Kashmir poses no difficulty in color grading using GemDialogue®.
Rubin, who passed away early in 2012, leaves a legacy to the gemstone industry for the future. GemDialogue® is currently available and in addition to the Color Chart Manual it now contains the GemDialogue® Color ToolBox, Grading Manual, and an instructional CD.
