The word orb comes to mind when I see this fob on a chain - maybe it could hypnotize you! Naw, too small - about 1/2 inch in diameter. Gold finished bottom has a textured gold colored cap The decorations of 2 circles and 2 crosses are rolled gold. 3 inch chain and swivel are gold-filled and show the usual wear. I would wear this orb on a chain as a pendant but a guy, especially a collector, might have other ideas.
