October’s birthstone opal is exceptional for a number of reasons. From the special meaning this gemstone is thought to have to its gorgeous and unique coloring, which allows it to seamlessly match just about any outfit in your closet, opal is the birthstone you need no matter when you are born.
Opal, the October birthstone, is known for its unique myriad of rainbow colors and milky shine. This gemstone’s kaleidoscope of colors is a result of light refraction. Rainwater is absorbed into the gemstone’s structure, and after years of pressure and heat, the water evaporates, and we are left with the gorgeous Opals we know today. The unique coloring of Opals is thanks to this formation.

A Brief History of the October Birthstone
The use of Opal as a birthstone goes back as far as the 15th century. Known in India as upala, or precious stone in Sanskirt, upala became opalus in Ancient Rome, also meaning precious stone, and leading to the name we know today.
In addition to the ancient Greek and Roman beliefs mentioned earlier, Opals have been part of beliefs across the world, with many cultures crediting the gemstone with a variety of powers.
Arabic legends are said to believe the gemstone came from the heavens in the form of lightning. Today, there are those who believe it is unlucky for someone not born in October to sport this gemstone (but we say it’s worth the risk!).
Opals are now primarily found in Australia but have also been discovered throughout the world.
