Yellow diamond comparison stones

[diamondliz]

I was wondering if yellow diamond comparison stones exist? If so, does anyone know where I can get a set?

I've heard (but I can't find on their website) that GIA sells sets of stones for their D-Z diamond scale but not for their colored diamond scale.
Even in the relatively affordable hue of yellow such a set would be VERY expensive because GIA has nine Color/Tone/Saturations grades for each hue and each grade would need a several diamonds to represent all the possibilities in only one of the grades - such as Fancy Intense Yellow.

Of course a printed chart is not as good as real diamonds, but it may be better than nothing.
They do sell a stand-alone chart for pink diamonds.
To get their yellow chart you must buy their $20 book containing charts of many colors.

"The GIA Colored Diamonds Color Reference Charts booklet explains and illustrates GIA color grades and descriptions for the most common fancy colors, including yellow, pink, blue, and yellow-green."

A person who makes very informative posts on this forum made a very informative post in a different venue. I can't link to it because of forum rules. But the answer to your question is that you buy your own stones and send them to GIA and AGL to be graded. No one makes a CZ fancy color master.
