4.65ct Oregon Fire Opal with play of color

This stone needs to be in a custom pendant or ring.  Look at that slight color play of green and red with the overall golden color. 
Oregon Fire Opal,  that "other" Oregon gemstone I deal in can be absolutely beautiful,  and I've gotten some to work with that has amazing play of color.  This is old stock material and very stable. 
Cut into a superman shield shape,  this stone gleams and glows with some amazing opalescence. 
This particular stone weighs 4.65ct and measures 19x15mm.
