Arizona Petrified Wood Height: Approximately 28 cm (including base) Width: Approximately 38 cm Thickness: Approximately 5 cm Weight: Approximately 13 kg A pamphlet from the time of purchase is included, but it is not a certificate of authenticity. Purchased a long time ago and stored for a long period. The first photo is the front, and the second photo is the back. It's difficult to see in the photos, but the back surface doesn't have much luster. The area in photos 7 and 8 is the thin part on the right edge of the first photo, but there is a 1.2 cm chip on the back. Please consider the above photos and only purchase if you agree.
