New York: 23 January 2019 -  The ColorCodex™ color referencing system is an innovative tool for industry professionals to compare and reference the color of faceted gemstones. Easy to use and intuitive, the ColorCodex™ system has been developed to allow for accurate and repeatable results when assessing the color of a gemstone.

 “In transparent faceted gems, cutting will create brightened reflections of brilliance and color as well as blackened areas of extinction,” explained Christopher P. Smith, developer of the system, “The ColorCodex system was specifically engineered to mimic this appearance and present color more as we see it in gems.”

The ColorCodex™ concept was originally announced at the AGTA GemFair in 2017. Since that time, the system has progressed into a powerful tool for industry professionals. Tested in development by prominent gem dealers, market analysts and major international laboratories, the ColorCodex™ is the most accurate system available today for referencing the color of gems.

Each ColorCodex™ reference is presented in a precise numeric code without the introduction of color descriptions. Numeric codes are not influenced by how individuals learn to describe color, nor cultural or geographical considerations. By eliminating the ambiguity inherent in color terminology, the ColorCodex™ empowers users to utilize the color designations for a wide range of applications.

“The ColorCodex system has the potential to bring a level of standardization that has up to now not been possible in the colored stone industry”, stated BJ Hackman of InterColor Inc and past ICA President, “And could fundamentally change how the industry handles the issue of color nomenclature.”

Applications for the system include:

  • Appraisers – to assign color reference independently for value, without relying on trade or market lexicon

  • Gem dealers and suppliers – to better match stones and fulfill inquiries

  • Education – to train new gemologists in the nuances of color in various gem species
    and varieties as well as how the influence of tone may impact their color appearance

  • Trade organizations – to provide a better understanding of gem varieties and trade terms

  • Laboratories – to establish better criterion and consistency of color descriptions, varietal calls and trade terms

 “ColorCodex is a fantastic tool for the jewelry industry and its consumers,” Joanna Hardy, noted author, gemologist and appraiser indicated, “while importantly not impeding the magic and emotionally charged stories that surround every colored gemstone.”
