I haven't seen one up close and personal, but having owned that MIA Standard Jazz for a while, there is a faint trace of gold-flake mixed into the green. That's probably what gives it the Jade Metallic sheen.
I'm not 100% sure, but I may have found a similar shade in
Subaru's "Autumn Green Metallic" finish. It, too, has a color-shift effect, depending on how the light hits it. To that effect, I may use it in a Fender Jazz refinish sometime in the future, only with gold hardware, instead of chrome.
