Rare Baby Blue Petrified Palm Wood

Rare Baby blue agate dots Petrified Palm wood slab.  
This palm slab has blue agate dots in the black wood and has brown outside bark surrounding it. I have never come across the blue agate dots in palm wood, extremely rare.   Not very much palm wood is found in Colorado but a few are out there.  This piece is one of a kind. 
 
Measurements are about: 4 1/2 inches x 2 inches x 6.8 mm thick.
