What Colors Are October Birthstones?

Opal, known for its unique play of colors, can display a mesmerizing array of hues—ranging from soft pastels like white, pink, and blue, to more intense shades such as fiery red, orange, and even black, with all these colors often appearing in one stone.
Tourmaline, on the other hand, is famous for its variety of vivid colors, including rich reds (rubellite), deep greens (chrome tourmaline), stunning blues (indicolite), and even multi-colored stones like watermelon tourmaline, which showcase pink, green, and white in a single gem.

These gemstones are not tied to specific days, so anyone born in October can enjoy the unique beauty and significance of these birthstones throughout the whole month.
Myths and History of October Birthstones
The usage of opals, as well as people’s deep appreciation for them, can be traced back to Ancient Rome. Since it can display a wide variety of colors at once, opal’s connotation was always related to magic, mental strength, and the supernatural.
Due to their colorful properties, opals are associated with volcanoes, the moon, lightning, fireworks, constellations, and galaxies. They inspired writers, poets, and painters and were especially favorable to royalty. Opals are even the national gemstone of Australia. Today, opals are a symbol of purity, hope, and abundance.
The name tourmaline means “unknown gemstone of mixed colors,” a term from Sri Lanka. Tourmalines have been mistaken for other colorful gemstones for centuries. Since they occur in virtually any color, people thought they were emeralds, rubies, sapphires, and other gemstones. It wasn’t until the 1800s that tourmalines were classified as separate mineral groups. For example, a recent discovery brought proof that some of the famous Russian crown jewels were, in fact, tourmalines and not rubies.
What sets tourmaline apart from all other colored gemstones is that it can be electrically charged. Due to its pyroelectric properties, it earned the nickname “the Ceylonese Sri Lankan Magnet.” The most common tourmalines are black.
Interesting Factoid: The first-ever tourmalines were thought to be “Brazilian emeralds.”
Mining Locations of Opal and Tourmaline
The main sources of opal are mines in Australia and Ethiopia.
Australia, specifically, has produced up to 95% of precious opals in the whole world. In fact, opal is the national gem of Australia.
The Australian mine that produces the majority of opals is Coober Pedy. The Coober Pedy is the mine of the largest opal discovery, the Olympic Australis. Weighing approximately 17,000 carats, this single opal has a value of AUD$2.5m.
Aside from Australia and Ethiopia, opal deposits mines are in the Virgin Valley in Nevada, the Czech Republic, Mexico, Indonesia, Canada, Idaho, Slovakia, Turkey, Brazil, Hungary, and many other places.
Rock opals can occur almost anywhere, including sandstone, limonite, marland, basalt, and rhyolite.
The main source of tourmaline is Brazil, which has a record of producing tourmalines in almost every color. Other mining locations of the tourmaline include Maine, Nigeria, California, India, Mozambique, Sri Lanka, Tanzania, Indonesia, Kenya, Malawi, Namibia, Madagascar, Pakistan, and other countries. All these deposits produced tourmalines of different colors. For example, the tourmalines that come from Maine are either pink or green. Californian tourmalines have a combination of these two colors, otherwise known as bi-colors.
A new and recently found type of tourmaline called Paraiba tourmaline mainly comes from Brazil. They’re bright blue and bright green, and experts consider them to be the most valuable type of tourmaline.
October Birthstones in Jewelry
Opals have been worn in jewelry for thousands of years. The earliest opal artifacts ever found date back to 4000 BC, and they’re believed to come from Kenya. Even to this day, they are very popular because of their intricate patterns. People love wearing opal jewelry because no two opals are the same, making each piece of jewelry completely unique.
Precious opals are often worn as rings, brooches, earrings, and necklaces. The bigger the stone, the better its play-of-color. They’re usually cut in a way to maximize the color-changing pattern, even if it makes the opal disproportional. Opals that have a dome-shaped surface are also the best cut for the play-of-color. Depending on their colors, opals can be paired with both silver and yellow gold.
When it comes to tourmalines, it’s all about the intensity of the color. Red and pink tourmalines, as well as Paraiba tourmalines, are the most popular choices for jewelry. Paraiba tourmalines usually have a custom cut, due to their color pattern and high value. Common cuts for tourmalines include pear, oval, and brilliant cuts. They can also be fashioned into long rectangles. Due to its diversity, tourmalines can be worn as rings, necklaces, pendants, brooches, earrings, and bracelets.
Shopping Tips for October Birthstones
Shopping Tips for Opals
When purchasing opal jewelry, it’s important to consider the stone’s unique characteristics to ensure you’re getting the best quality and value. Here are some key tips to keep in mind:
- Check for color play: The most valuable opals exhibit a strong, vibrant play of colors. Look for stones that showcase a variety of colors from different angles.
- Consider opal type: White opals are more affordable, while black and fire opals tend to be rarer and more expensive. Choose the type that fits your style and budget.
- Opal size matters: Larger opals can be more expensive, but smaller opals can still offer stunning color displays. Focus on the quality of the color rather than size alone.
- Avoid exposure to heat: Opals are sensitive to temperature changes and can crack. When purchasing, ask about proper care instructions to keep your opal safe.
- Look for secure settings: Because opals are softer stones (5.5-6.5 on the Mohs scale), ensure the jewelry setting provides good protection, especially for rings.
- Opt for treated vs. untreated opals: Some opals are treated to enhance their color. Natural, untreated opals are often more valuable, so confirm with your jeweler.
- Evaluate clarity and transparency: A top-quality opal may be translucent or semi-transparent, enhancing its vibrant color play. Opaque opals are typically more affordable.
Shopping Tips for Tourmalines
Tourmaline’s wide range of colors and relatively durable nature make it a popular choice for jewelry, but there are a few factors to consider when shopping for this gemstone. Here’s what to keep in mind:
- Choose your color: Tourmaline comes in a wide variety of colors, from rubellite (red) to indicolite (blue) and beyond. Pick a shade that resonates with the recipient’s personal taste.
- Examine clarity: Tourmalines generally have good clarity, but some inclusions can affect the stone’s brilliance. Choose stones with minimal inclusions for a more dazzling appearance.
- Consider cut: Tourmalines are often cut in ways that enhance their natural color. Look for well-cut stones that maximize the stone’s light reflection and overall beauty.
- Check for durability: Tourmaline is relatively durable with a Mohs hardness of 7-7.5, making it suitable for everyday wear. Ensure the setting complements this durability for rings or bracelets.
- Understand rarity: Certain types of tourmaline, like Paraíba and rubellite, are rarer and more expensive. If you’re looking for a unique, high-end gift, these varieties are excellent choices.
- Watch for treatments: Some tourmalines are heat-treated to enhance their color. Make sure you’re informed about any treatments, as untreated stones may carry higher value.
- Select multi-color options: Watermelon tourmaline, with its stunning mix of pink and green, offers a distinctive and eye-catching alternative to single-color stones, making it a fun and unique gift.
How to Clean Your October Birthstone Jewelry
Cleaning opal and tourmaline jewelry requires special care to maintain their beauty and prevent damage.
For opals, avoid using harsh chemicals or ultrasonic cleaners, as these can cause cracking. Instead, gently clean your opal jewelry with warm, soapy water and a soft cloth.
Tourmaline is more durable, but it’s still best to avoid ultrasonic cleaners. Clean tourmaline jewelry with mild soap, warm water, and a soft brush to remove dirt from the crevices.
Always dry your jewelry thoroughly and store it separately to avoid scratching or damage.
