Colour and Types of Opals: From Ethiopian to Australian and Beyond

Opals are one of the most beautiful gemstones in the world. They are special because they have a rainbow-like play of colors that change when you move them. This sparkling effect makes opals unique and loved by many people. There are many types of opals, and they come from different parts of the world. In this article, we will explore the colors and types of opals, including Ethiopian opals, Australian opals, fire opals, and Mexican opals. Let’s dive in and learn about these stunning stones in easy words!

What Makes Opals Special?

Opals are formed deep inside the Earth. They are made from water and silica, a type of mineral. When water carrying silica seeps into cracks in rocks, it hardens over thousands of years to create opals.

The most amazing thing about opals is their colors. This is called the “play of color.” When light passes through tiny silica spheres in the stone, it splits into different colors. This is why opals can show all the colors of the rainbow!
