Ethiopian vs Australian :- The first thing to note about these two types of opal is where they came from. Every nation generates distinctive gems that are exclusive to its area because of variations in geology. For example, Australian Opals originate in the Cretaceous rock layer beneath the Earth's surface, but Ethiopian Opals come from Ethiopia's steep hills.
In the realm of gemstones, opal stands tall as one of the world's six acknowledged precious stones, proudly asserting its prestige alongside diamonds, rubies, sapphires, emeralds, and pearls. With an extraordinary allure, opal hails predominantly from Australia, constituting over 90% of the globe's prized opal reservoir.
