Jet is a form of fossilized coal. Wood submersed in stagnating waters and then compressed over millions of years formed this velvety black organic material. This specific variety of jet is from Pennsylvania, carves beautifully and takes to polishing quite well, as seen in Keli'i Eli's poised roadrunner. This fast-running ground cuckoo is New Mexico's state bird. An elegant and lustrous beak, enchanted eyes of inlaid lapis lazuli and a matrix-rich turquoise base all make for a museum-quality fetish. About 3 1/2" long, 1 3/4" wide and 2 5/8" tall, measurements include the handsome base.
