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.
