This is a beautifully polished bone specimen with yellow, burgundy, red, clear, grey and brown cells. The cell structure varies from a very tight, small pattern to large floating cells. This piece will be a great addition to any collection - a great conversation piece as well. It measures 7.5" x 6.5" x 1.5" at the thickest part. It is only polished on the front. More pictures available on request.
