LARGE brown Agate Geode polished slab 6x4.75x.75" THICK CUT

LARGE brown Agate Geode polished slab 6x4.75x.75" THICK CUT I'm not exactly sure what this stone is - it was part of a collection my grandfather gave me as I was growing up... gorgeous natural color tones, white and brown hues. Measures approx 6x4.75 and .5-.75” thick, it's a nice thick cut.  Weighs approx 1# 5oz.  Felt back. $20 NOT INCLUDED - For size ref only!
