We all have a brain, but now you can have two! Or one and a half, if you want to be exact. This delightful hemisphere was cast in solid pewter from a hand carved model. The pendant is two-sided, so you can decide which faces out. It measures about 3/4" square (20mm) and is hung on a 24" gunmetal chain or an 18" sterling silver chain. Using the greatest attention to detail, it displays a wide range of brain features, including the: corpus callosum, thalamus, hypothalamus, medulla oblongata, cerebellum, brainstem... and more.
