Opal is perhaps the most famous of October’s birthstones. Known for its amazing play-of-color, opal can display a wide variety of colors that seem to shift and change as you move the stone. Opals are unique because they don’t have a crystal structure like most other gemstones. Instead, they are made of tiny silica spheres that reflect and scatter light, creating a rainbow of colors. Let’s break down what makes opal so special.
- What is Opal?
Opal is a gemstone made from silica, which is a common mineral found in sand. However, unlike regular sand, opal forms when water mixes with silica and slowly hardens over time. This gives opal its unique appearance. - Different Types of Opals
Opals come in many different varieties, and each type has its own special features:- White Opal: This is the most common type, with a light, milky appearance and flashes of color.
- Black Opal: The rarest and most valuable type, black opals have a dark background that makes the colors stand out more.
- Fire Opal: Unlike most opals, fire opals are known for their bright orange, yellow, or red colors. They don’t always have the play-of-color seen in other opals.
- Boulder Opal: These opals are found attached to their original rock (called the matrix), which gives them a unique look.
- Crystal Opal: These opals are transparent or semi-transparent and show an incredible play-of-color.
- How Opals Are Formed
Opals form when water flows through the earth and picks up silica from sandstone. Over millions of years, the silica-rich water fills cracks and spaces in the ground. As the water evaporates, it leaves behind solid opal. This process is what creates opal’s unique structure and its ability to reflect light in so many different ways.
The Symbolism and Meaning of Opal
Opal has been admired for centuries not just for its beauty, but for its deep symbolic meanings. People have believed that opals can help with emotional healing, creativity, and spiritual protection. Let’s explore what opal represents and how people use it to improve their lives.

- Artists, writers, and musicians might wear opal jewelry to help inspire their work.

The Colors of Opal: A Visual Symphony
One of the most amazing things about opal is its colors. When you look at an opal, it can appear to flash with every color of the rainbow. This effect is called “play-of-color,” and it happens because of the way light passes through the tiny silica spheres inside the opal. Different types of opals display different colors, but all of them are beautiful in their own way.
- How Opal Gets Its Colors
- The colors in opal come from the way light bends and reflects off the tiny silica spheres inside the stone.
- The size and arrangement of these spheres affect what colors you see. Smaller spheres create blue and violet colors, while larger spheres produce red and orange.
- The Rarity of Black Opals
- Black opals are the rarest and most valuable type of opal.
- Their dark background makes the play-of-color stand out more vividly, creating a striking contrast.
- Black opals are mostly found in Australia, which is famous for producing the finest opals in the world.

Tourmaline is the second birthstone for October, and it is just as fascinating as opal.

Let’s dive into the details of this colorful stone.

The Science Behind Opal’s Play-of-Color
Opal’s unique display of colors, known as “play-of-color,” is one of the most intriguing aspects of this gemstone. This phenomenon occurs because of the way light interacts with the internal structure of the opal.
- Understanding Opal’s Structure
- Silica Spheres: Opal’s play-of-color comes from the tiny silica spheres packed together in a regular pattern. Light bends and reflects off these spheres, creating different colors.
- Light Diffraction: The size and arrangement of the silica spheres affect how light is diffracted, or split into its component colors. Smaller spheres produce blues and greens, while larger ones create reds and oranges.
- Factors Affecting Opal’s Appearance
- Opacity: Opals can be transparent, translucent, or opaque. The transparency affects how light passes through the stone and enhances its colors.
- Background Color: The color of the opal’s base, or body tone, impacts the play-of-color. For example, a black opal’s dark background makes its colors appear more vibrant and intense.
Tourmaline’s Unique Properties
