I bought this beauty of ebay a few years ago. What great colors! It is time for someone else to add this to their collection as I am downsizing mine. 1"x7/8".Thanks For Looking! I am not positive, but I do believe that the face of this agate may of had some work done to it. T are no grinding marks or anything else like that. Please ask questions as bid is final! This is still an amazing stone even if it has been worked a little.
