Opals: The Playful Gemstone Full of Color and Magic

Opals are one of nature's most dazzling creations, and there's no mistaking their signature play of color. When you look into an opal, it feels like you’re holding a piece of the rainbow itself. Whether it's the fiery reds and oranges or the deep blues and greens, opals offer a mesmerizing, kaleidoscopic display that’s truly one-of-a-kind. It’s no wonder they’ve been adored by cultures worldwide for centuries.

What Makes Opals So Special?

Opals are formed from silica, the same substance found in sand. Over thousands (sometimes millions!) of years, water seeps into the earth, carrying silica deposits. These deposits slowly form into opal, filling cracks and voids in rocks. Over time, as the silica builds up and water evaporates, these deposits become beautiful opal gemstones. As the spheres of silica diffract white light, breaking it into the many colors of the spectrum, we see the phenomenon called opalescence.

Opals Prized Throughout History: Symbol of Good Luck and Protection

People have prized opals for thousands of years, with their allure dating back to ancient civilizations. The Romans, for instance, valued opals as highly as diamonds, believing the stone symbolized hope and purity. Additionally, in ancient Greece, opals were thought to give their wearers prophetic powers and protection from disease. Opals were also cherished in the Middle Ages, where they were considered a symbol of good luck and thought to hold all the virtues of other gemstones due to their rainbow-like play of color. Throughout history, opals have been admired for their beauty, mystique, and the belief that they hold magical and protective powers.

The Modern Meaning of Opals: Creativity, Emotion, and Transformation

Today, opals are still cherished for their beauty, but they also carry deep symbolic meaning. They are the birthstone for the month of October. Many people believe that opals inspire creativity and enhance imagination, making them popular among artists and dreamers. They're often associated with emotions and passion, as their shifting colors are seen to reflect the changing nature of feelings and inner energy. Opals are also thought to bring good luck, protection, and even promote personal growth and transformation. Whether for their vibrant appearance or their symbolism, opals continue to be seen as stones of inspiration, individuality, and emotional balance in modern times.

Types of Opals

Opals come in many shapes, forms, and colors. These include: white, orange, yellow, red, blue, green, purple, grey, brown and black. While all opals share an iridescent beauty, there are many types to explore. What kind will speak to you?

Boulder Opal

Around 95% of the world's opal supply comes from Australia. Australian Boulder Opal forms in the cracks and cavities of ironstone boulders, making it truly unique. Primarily found in Queensland, this opal showcases vibrant flashes of color set against the earthy tones of the host rock. The stunning contrast between the opal’s fiery hues and the ironstone creates a captivating visual effect. Its natural setting enhances its play of color, revealing brilliant blues, greens, purples, and reds within. Boulder Opal is especially prized for its durability. The rugged, organic feel of each stone makes boulder opals a favorite for those who appreciate jewelry with a natural, earthy vibe.

Cantera Opal

Cantera Opal is a unique gem from Mexico, found within rhyolite stone. Unlike other opals, Cantera Opals remain partially encased in this matrix, creating a stunning contrast between the fiery iridescence of the opal and the earthy tones of the stone. These opals are softer and more crystalline than other types, showcasing a vibrant play of color that often includes brilliant reds, oranges, and a full spectrum of hues. Their natural, uncut appearance makes Cantera Opals highly prized among collectors and jewelry makers alike. With their organic beauty and rich cultural heritage, these gems are a true treasure!

Ethiopian Opal

Ethiopian Opals are a true wonder of the gemstone world, known for their vibrant play of color and mesmerizing transparency. These opals are primarily found in the Welo region. They often have a lighter body tone, allowing their fiery flashes of reds, oranges, blues, and greens to shine through beautifully. What makes Ethiopian opals especially captivating is their ability to absorb water. Because of this, they are often nicknamed jelly opals. Like many more mundane rocks, their colors even more dynamic when wet. Ethiopian Opals are prized for their stunning, ethereal glow. Each stone seems to have a life of its own, constantly shifting and shimmering with every movement. If you're looking for a gem that's full of energy and charm, Ethiopian opals are a perfect choice.

Lab Simulated Opal

Lab-simulated opals are a fantastic option for anyone who loves the beauty of opals but is looking for a more affordable and environmentally friendly choice. These opals are created in a controlled environment, mimicking the natural process that forms opals, but in a fraction of the time. The result? Gorgeous stones that still display the signature play of color, with flashes of vibrant reds, blues, greens, and more. What’s great about lab-simulated opals is that they are just as captivating and durable as their natural counterparts, making them perfect for everyday wear. Plus, they allow jewelry lovers to enjoy the magic of opals without the higher price tag or environmental impact.

Dendritic Opal

Dendritic opal is a fascinating and unique variety of opal that captures the beauty of nature in every stone. Unlike other opals known for their play of color, dendritic opals are prized for their intricate, tree-like patterns that resemble delicate branches or ferns. These dark, organic inclusions are formed by minerals like manganese or iron, giving each stone a one-of-a-kind appearance. With their calming, earthy vibe, dendritic opals are perfect for those who love subtle, natural beauty. Whether set in a pendant or ring, these stones offer a peaceful, grounding energy that makes them stand out in any jewelry collection.

 Caring for Your Opal Jewelry

Opals are delicate gems. The silica in opals contains as much as 20% water, which means they may dry out if left in a warm environment. Try to avoid very high temperatures or low humidity extremes, such as boiling water or zero humidity. Avoid letting opals come in contact with bleach, chemicals and cleaners, swimming pools and spas. It is best to take off your jewelry when putting on lotions or perfumes.  

Opals can be cleaned gently with a soft cloth. Never clean your opal in an ultrasonic cleaner, as the intense vibrations may cause cracking. 

Store your opal jewelry in a jewelry box or safe place. Putting it in a zip bag will help reduce tarnish. 

Why We Love Opals
