When a gray or grayish hue is present as a third color in a diamond, from a price perspective it eliminates almost entirely the influence of the first color moderator. It also discount the value of the diamond considerably. Depending on the stone's primary color, the reduction in value could be as high as 70 percent.  


The missing gap: bridging gemology and reality  
You are qualified to determine the identity of a gemstone, but what does that provide you in the real world? Do you know that a ruby may vary in price from $10 per carat to almost $1 million dollars per carat? How can you learn what really counts. 

Is the future of gem pricing already here?   
One of the most difficult tasks in the gem business was forever simplified with the introduction of GemePrice, an online pricing system that can accurately value a colored diamond or gemstone in real time.  Its fourth generation has just been released and includes a range of new features for jewelers, gem dealers, designers, gemologists and appraisers.
