Over 1400 Colors Available

Two years in development, this new color communication system, based on Munsell has over 1,400 colors in this master comparison book of colors. Each of 40 pages has its own unique overlay chart, developed by color specialists and adapted for use in the jewelry industry by our own team of experts. The transparent overlay chart gives the name of the color.

Gem Crown and Supplemental Book

That will contain usage information along with extensive grading charts that will correlate the World of Color selections with the GemGuide pricing 1-10 grading scale. Now you can more accurately describe, grade, and price all colored gems.

The samples shown here are not true color; they are only to give an idea of what the pages will look like. The overlay page is a transparent sheet that will name the color for the user. The supplemental book contains the grading numbers.
