Quick Answer: The traditional October birthstone is opal, a gemstone known for its colorful play-of-color. Tourmaline is also recognized as a modern October birthstone. Opal is commonly associated with hope, creativity, purity, emotional expression, and inspiration.
What is the October Birthstone?
The most popular birthstone for October is opal. This gemstone is famous for its shifting flashes of color, often called “play-of-color.” Depending on the stone, opal can display shades of blue, green, orange, yellow, pink, red, and violet, sometimes all within the same gem.
Opal has long been admired for its soft glow and rainbow-like beauty. It is often chosen for October birthstone jewelry, including rings, earrings, necklaces, and bracelets.
Is Opal the Only October Birthstone?
No. October has two widely recognized birthstones: opal and tourmaline. Opal is the traditional October birthstone, while tourmaline is also accepted as a modern October birthstone. Both stones are known for their wide range of colors, making October one of the most colorful birthstone months.
If you love soft rainbow flashes and a dreamy look, opal is a beautiful choice. If you prefer a gemstone that comes in many bold colors and is generally better suited for regular wear, tourmaline may also be worth considering.

What is Opal?
Opal is a gemstone made of hydrated silica. Unlike many gemstones that have a crystal structure, opal has a unique internal structure that can diffract light and create its famous play-of-color. This is what gives precious opal its glowing, multicolor effect.
Opal is sometimes called the “Queen of Gems” because one stone can show many colors at once. Some opals have bright rainbow flashes, while others have a soft milky appearance or warm fire-like tones.
There are two broad categories of opal:
- Precious Opal: Shows visible play-of-color, meaning flashes of different colors appear when the stone moves under light.
- Common Opal: Usually does not show strong play-of-color but may have a soft, smooth, or milky glow.
October Birthstone Meaning and Symbolism
Opal is commonly associated with hope, purity, creativity, love, emotional expression, and inspiration. Because of its colorful appearance, many people see opal as a symbol of imagination and individuality.
Throughout history, opals have been admired as mysterious and lucky stones. Some traditions believed opal could bring confidence, passion, and positive energy to the wearer. Today, many people choose opal jewelry because it feels meaningful, artistic, and deeply personal.

Types of Opal
Every opal is unique. Two opals are rarely exactly alike because each stone has its own body color, pattern, brightness, and play-of-color. Below are some of the most popular types of opal used in jewelry.
Fire Opal
Fire opal is known for its warm orange, yellow, and red colors. Unlike many precious opals, some fire opals may not show strong play-of-color, but they are admired for their bold and fiery appearance. Fire opals are often found in Mexico, Brazil, and Ethiopia.
Black Opal
Black opal is one of the rarest and most valuable types of opal. It has a dark body tone, usually ranging from dark gray to black. This dark background makes the flashes of color appear more intense and dramatic. Many fine black opals come from Lightning Ridge in Australia.
Ethiopian Opal
Ethiopian opal is admired for its bright play-of-color and unique patterns. Some Ethiopian opals may have a milky or translucent appearance, while others display vivid color flashes. Ethiopian opal has become popular in modern jewelry because of its beauty and variety.
Water Opal
Water opal is usually colorless or very light in body tone, with a soft and delicate appearance. Some water opals show subtle play-of-color that changes depending on the angle of light. These opals can be found in countries such as Australia, Ethiopia, and Mexico.
White Opal
White opal, also known as milky opal, has a light or white body color. It may be translucent or opaque and can display soft multicolor flashes. White opal is a classic choice for elegant and feminine jewelry designs.
