This is a smaller pendant and would work best with 16" to about a 24" necklace design.
The donkey has been used as a working animal for at least 5000 years! There are over 40 million donkeys in the world...that's about one donkey for every 175 people. That's a lot of donkeys! A male donkey or ass is called a jack, a female a Jenny. So if you ever call a person a "Jack Ass", remember that this is gender specific.
