This very old Fairburn Agate, out of an old collection, is the posterchild for "Don't Judge A Book By Its Cover" !!! Natural on the top/outside showing disguise and natural patina millennia in the making, and polished on the bottom showing the beautiful interior with classic holly leaf type fortification and bandings. This is NOT a hills agate, and came out of the grasslands many decades ago from alluvial deposits which are the "original" Fairburns. Measures _________________.
