cab contest

Cab Contest: I made a cab out of this rare stone. Try to guess what it is.
First person to guess correctly will win this Morrisonite cab I made a few days ago.

Here are some small hints: It is a clear agate with a Chrysoprase blue/green color. A moss/dendrite. The rough never has fractures and never has pitting. Some old timers might know what this is since it has not been on the market since the 60's. Note: This rare piece will be for sale on my next web site sale on Sunday 4/27 @ 4:00pm MST.
