A sapphire ring with an incredibly detailed portrait that is 2,000 years old

This almost two thousand year old sapphire ring is not only aesthetically impeccable, it also has a fascinating history.

It is thought to have belonged to Caligula, the Roman tyrant and his illustrious emperor. The reign was short-lived and ended with the assassination of Caligula by the Praetorian Guard.

How did people of that era have the means to make such a work of art?
