Gemstone Color Testing
Filed in archive Gemstones by tammy on May 30, 2006
in gemstones is really a critical part of the job. Yes, there's clarity and those other C's, but color I think is super important. I know for me, when I'm buying gemstones, that's pretty much the first thing I consider. I mean. An amethyst, for example, can be clear as a bell, but it's not the right color, who cares?It never occurred to me until I read this on National Jeweler that some gemologists may have issues judging color accurately.
My poor dad is colored blind. It is really amazing to see the kinds of clothes he puts together. True, he's a severe case, but even a little trouble distinguishing color and shades can be a big problem for a jeweler.
Luckily, they actually have a test for jewelers and gemologists.
More from National Jeweler: The American Gem Society (AGS) will introduce a new, improved version of its color deficiency screening, designed to identify how well appraisers and jewelers judge color, at the JCK show in Las Vegas.
The Colorvision screening is used to detect color perception deficiencies that could affect color judgment, and is requirement for all of AGS' certified gemologist appraisers. It is also recommended for all professional appraisers or anyone engaged in buying, evaluating or valuing colored gemstones or fancy-colored diamonds
The HRR 4th edition Pseudoisochromatic Test for color deficiency screening provides valuable knowledge for professional appraisers or anyone engaged in the purchase, evaluation or valuation of colored gemstones or fancy colored diamonds.
