Actually I was referring to pure garnets in my post in regards to their value and color desirability and how the less desirable and valuable colors in the pinkish hues are often mistaken for rubies as it applied to this thread directly. As for the ultra rare, far generally lesser known about and more valuable, colors changers they are not pure garnet but are actually a hybrid mix of spessartite and pyrope garnet and in many cases, may also contain traces of glossularite or almondine garnet. So they are not pure garnet to which I was referring to in my post.
