They are very interesting.
In my experience too, chrysoprase have been very stable despite its reputation for fading.
I mounted some for clients that lived by the beach in hot sunny climates and when I saw them years later, I did not notice any change in the color. These were both old German saturated chrysoprase and top Australian highly translucent material that I happen to be so found of...

This is the good news!!!!
