In 2001, archaeologists stumbled upon an ancient Roman tomb. B | Forbidden History

In 2001, archaeologists stumbled upon an ancient Roman tomb. But it wasn't the bodies they found that attracted the most attention, but one unusual ring. A portrait was carved inside the stone, and the jeweler covered it with the purest rock crystal. The lens effect and blurred facial boundaries give a kind of 3D effect.

One small piece of jewelry and a tangible evidence of the level of technological development. Can underdeveloped and incompetent people create something like this?
