October Birthstone: Opal

Every birth month is connected to a different gemstone. Those lucky enough to have an October birthday get to enjoy the mesmerizing opal as their birthstone. Opals are known for the range of shimmering colors that dance across their surface and create a striking optical effect. October’s birthstone is popular in necklaces, rings, bracelets, earrings and more.

A Galaxy in a Stone

Opal was admired by many cultures throughout the ancient world, each giving it a unique meaning. In Arabic lore, opals fell from heaven in the form of lightning, while the Greeks believed they could protect against disease and bestow the gift of prophecy. Opal's shifting rainbow of colors has inspired writers to compare it to volcanos, fireworks, galaxies and more.

Opal's Birthstone History

When people first began wearing the stones connected to their birth months in the 16th century, opal was selected as the original October birthstone. The National Association of Jewelers also chose opal as the modern October birthstone in 1912. 

 Historically, opals have been revered throughout many cultures. They have been linked to the symbolism of luck, love and even a person’s ever-changing moods. This October birthstone is often found in Australia, Mexico, Ethiopia, Brazil and the United States. 


October Birthstone Color

Opal gemstones offer incredible colors and unique sparkle. October’s birthstone sparkles with a soft or translucent base color that is accented by specks of color dancing throughout the gem. This phenomenon, known as play-of-color, makes every piece of opal gemstone jewelry extraordinary. 

October Birthstone Meaning

Each birthstone has its own meaning and symbolism. Opals are associated with love, hope, faith, loyalty, purity and truth. Through its rainbow of colors, this gemstone is thought to reflect the mood of the wearer, to help release inhibitions and to enhance beauty. Some believe that opal symbolizes the virtues of all colored gemstones, making it one of the luckiest gemstones to wear. 

Opal’s Ties to October

There are many zodiac gemstones that are tied to star signs. While opals aren’t directly tied to the zodiac signs of people born in October, they do represent some of their characteristics. Libras, the first sign in October, are known for their ability to fit into any situation. Social shape-shifting Libras are well-represented by the color-shifting-play offered by opals. The fiery passion of Scorpios is present in the glowing specks of color that punctuate many October birthstones. 

The Lucky Birthstone

Ancient Romans valued opals as stones of good luck. Opals are especially lucky as the October gemstone and are believed to bring good fortune to people who were born in this month.

October Birthstone Buying Tips

When buying the colorful birthstone for October, it’s important to purchase from trustworthy jewelers to ensure you’re finding a high-quality gemstone. There are several types of opals to choose from, each bringing its own unique variations on this gem’s iconic play-of-color. When buying October birthstone jewelry, consider these tips:

Choose the color that best fits your budget. Rarer October gemstone colors, such as black opals, will command higher prices than more commonly found varieties of this birthstone.
Maximize budgets by mixing gemstones. If a large opal is out of the budget, consider adding additional gems into the mix, such as white sapphire. This can create a dynamic piece that adds additional sparkle while keeping your budget in mind.
Pick a setting that strengthens the opal. October’s gemstone can be more fragile than other birthstones, so choose a setting type that’s best to protect the stone. This may include a bezel setting or a halo of other gems to encase the opal. Pick a setting that strengthens the opal. 

Purchasing enhanced October birthstones is a great way to enjoy a durable gem with incredible paly-of-color. Enhancements may include colorless hardeners to improve the gem’s durability and color. More translucent October opals may also receive backings to improve rigidity.

Additional October Birthstone

While opal has long reigned as the true October birthstone, some people are beginning to consider tourmaline a significant stone for the month. Tourmaline jewelry is an increasingly popular alternative to opal that offers beautiful pink hues and lasting styles.
