This shell is about 13" X 9" at the longest points. It is about 3" at the highest point. It weighs 2 pounds, 14.6 Ounces on my scale. In my eyes it has an off - white color to it ? The last two pictures show two chips on the inside edges. There are some smalls chips on the edges in the other pictures. It is still a vey nice specimen. Thanks for looking and if you have any questions just ask.
