Opal: The Dazzling October Birthstone

by Liz Beth |

If your birthday falls in October, you are fortunate to have one of the most bewitching and fascinating gemstones as your birthstone. Opal meaning is one that is full of mystique and hope, which is evident by its rich play of color.

Wearing October birthstone jewelry integrates the qualities of the stone with the person wearing it. Opal is also a birthstone for Cancer signs (those born between June 21st and July 22nd).  It is also the traditional gift for the 14th wedding anniversary.

We’re going to dig into the October birthstone meaning, but first, let’s discover the physical properties of Opal that cause such a splendorous display of color.

Physical Properties of Opal

Most Opal originates from Australia so it makes sense that it is their national gemstone. However, in 2008 there was a very significant event that happened in Wegel Tena, Ethiopia.  A deposit of incredibly vibrant Opal was discovered and named after the province in which it was founded.  This is known as Welo Opal and it’s the Opal that I use in my teardrop Opal pendant. 

Opal Structure, Color & Types

Most of the Opal meaning comes from its alluring display of color. It acts like a prism, absorbing and refracting light, resulting in its dance of color. This opalescent effect makes it look like the stone has different colors glowing from within it.

According to, Opals are amorphous, which means they don’t have a crystalline structure or a definite chemical composition. For this reason, it is called a mineraloid, not a mineral. Opals are composed of layers of hydrated silicon dioxide.

The colors in Opals don't come from pigments. Instead, they are optical effects that are caused from the hardening of the silica spheres that make up the stone. The spaces between the spheres create light diffraction that break up colors of the spectrum when light hits it.  Pink Opal is another popular color of this unique stone which exhibits a beautiful pale-pink matte finished color.   Here is a link to my raw gold-dipped pink Opal pendant necklace -it's definitely worth having in your jewelry box.

The flashes of light and colors in each stone are determined by the size of the spheres and the way they are packed into the stone.

Opals can be colorless, white, pink, red, orange, yellow, green, blue, brown, or black. They can be transparent, translucent, or opaque.

Origins of the Opal Name

When we look at Opal meaning, it helps to understand where the name came from.

The word “opal,” comes from the Latin word “opalus” as well as the Sanskrit word “upala,” which means “precious stone." It was known as "opallios" in Greek, which means "to see a change in color."

The Roman general, Mark Anthony, was said to have greatly admired an Opal that was owned by Senator Nonius because the flashes of lights reminded him of his nights with Cleopatra. However, the Senator refused to sell the stone and fled his home, leaving only with the Opal the hand.

Napoleon, the Emperor of France, gifted his Empress, Josephine, a Red Opal. It came to be known as "The Burning of Troy" as a result of its brilliant flashes.
