About This Quiz

Gemstones have long held a place of treasure for gods and humans over the centuries. Some stones, like the opal, represented hope and purity. Others like hematite had connections to mythological gods like Mars, the red god of war.

And in the modern day, we cherish gemstones for how they appear adorning our hands, wrists or necks.
