Zeide,

Sounds like Perlas is describing the same thing I saw, namely monochromatic overtone and a pink glow in transmitted light. I notice that hardly anyone has jumped in on this thread. I suspect that is because a lot of experts are confused about this distinction and, perhaps, too embarassed to admit it.

Be interested in Jeremy's opinion. His lovely "freshadamas" are very fine and have a distinct overtone but no affect that I would describe as "prismatic".

Shall we define our terms: prismatic (Webster) means; multicolored and irridescent, agreed? Irridescent really means the same thing, that is the showing of prismatic (rainbow) colors. Monochromatic means
one color, as single color.
