Each opal has its own uniqueness, but many might not know how they developed. Seasonal rains soaked the parched Outback in Australia, carrying silica deposits underground into cracks between layers of rock. When the water evaporated, these deposits formed opal. Sometimes, silica seeped into spaces around wood, seashells, and skeletons, resulting in opalized fossils.
About 95% of opal comes from Australia, however, a similar mineral has also been found on the red planet, Mars! According to NASA, the Martian rocks are light-toned and appear cream-colored, containing a hydrated mineral similar to opal.
For centuries, opals have been the star of many legends, including Greek mythology! Ancient Greeks believed that opal came from the tears of Zeus, the god of lightning, after winning a battle against the Titans. His joyful tears turned into opal when they landed upon Earth.
