Seal (device)
Signet rings were often worn on the little finger of either the right or left hand (depending on the country), although some countries have different customs (French and German noblemen, and some Spanish nobles wear it on the ring finger of their left hand; Swiss wear it on the ring finger of their right hand).  In the United Kingdom, signet rings are typically worn on the little finger of the left hand of the bearer and are often cast of gold. The ring is worn with the seal facing outwards so that the wearer can make a seal without taking the ring off.
