Opalescence is a popular tooth-whitening product that is used to improve the color of the teeth in individuals with stained or discolored teeth.

The appearance of opal that makes it easily recognizable is the play of colors or opalescence. What distinguishes opal from other stones is that it does not simply glow with a single hue but paints the full rainbow, which can change with the movement or when the light is thrown at it. This is called an optical effect, which is a result of the microscopic silica spheres within the stone reflecting light and creating these rainbows.

The change in colors can go from bold, bright, and overwhelming ones such as Red, Orange, blue, or green rather to faint shades of violet or yellow, respectively. It is interesting to note that every opal has different colors, and there are no two opals that are similar in color patterns. The intensity, pattern, and range of colors play an important role in making opal valuable and beautiful.

Originally, in ancient Europe, opals were believed to be lucky charms that had to do with the luck of the person wearing them.

Another gemstone that the opal was often worn by was Queen Victoria, who played a role in regenerating the passion for the gemstone in the 19th century. The monarch would assign this gemstone as one of her favorites and, thus, use the opal to give the prestige of the gemstone to her family and friends for many years.

In the past century, the discovery of opal in Australia at the end of the nineteenth century caused the world’s gemstone demand. Australia still ranks among the top producers of gemstones, especially opals, including black opals and boulder opals, which are favorite items for many collectors.

Opal’s Water Composition

Although opal is considered a gemstone that is formed exclusively of silicate minerals, it is composed of 3%-10% water, which adds even more to its enchanting look.

It consists of microspheres of silicon oxide, which are linked by water only. This water content, which varies between 3 % – and 21 %, is what causes opal to display its forbidden fire or play of colors.

Introduction to Opal Gemstone

One of the most interesting and colorfully beautiful gemstones in the marketplace, opal is a stunning find. None can compare to the vibrant colors and remarkable shifting patterns that it displays. While many flash colors, the opal holds the reputation of flashing colors and is thus considered the October birthstone, associated with creativity, passion, and emotional balance.

History of Opal Gemstone

Opal was an admired stone all throughout the history for its beauty and mystical energies. The term “opal” is given in honor of the Sanskrit word “Upala,” which means “precious stone,” and later, the Greek word “Opallios” means “to see a change in color.” In ancient Rome, it would symbolize love and hope. Opal was already believed to possess great powers during the Middle Age, when it was considered a talisman that could bring good fortune.
Throughout history, opals have been cherished by royalties, from Roman emperors to European queens who have collected some radiant stones. Modern times have seen Australia become the epicenter of opal mining. Today, it supplies almost 95% of the world’s opals.

Types of Opal Gemstones

Opal gemstones come in several varieties and have rather diverse characteristics. Let’s get into the types of opals and their unique properties.

Black Opal

Black opal is the most valuable and rarest variety of opal. It shows a dark body tone, which is black or dark grey coloring, to bring out vivid bright play-of-color. The deep background contrasts excellently with bright flashes of colors, so it’s easily understandable why black opals are so highly sought by collectors. The most famous black opals are those mined in Australia at Lightning Ridge.

Key Features:

• Dark body tone enhances the play-of-color.
• Costliest and rarest form of opal.
• Primarily found in Australia.

White Opal

White opal, or “milky opal,” has a light or white body tone. This type is more common than black opal and shows paler, watercolor-like flashes of color. The play-of-color in white opals is less bright, but they are popular for their delicate beauty.

Key Characteristics:

• Light or white body tone.
• Much more common and cheaper than black opal.
• Exhibits pastel tints in play-of-color.

Fire Opal

Unlike the standard variety of opals, fire opals cherish their body color that is ranging from yellow to orange to red. The term “fire” applies on the body color rather than the play-of-color, as this color play is normally absent or at minimal in fire opals. These gemstones are transparent to translucent and commonly found in Mexico.

Key Characteristics:

• Body tone is bright yellow, orange, or red.
• Little to no play-of-color.
• Mainly mined in Mexico.

Boulder Opal

Boulder opal forms inside cracks and crevices of ironstone boulders.

How to Identify Authentic Opal Gemstones

If you’re looking to purchase an opal gemstone, it’s important to know how to determine the authenticity of an opal from treated or synthetic stones. Here’s how to identify a real opal:

Look for Play-of-Color

The most important characteristic of a real opal is play-of-color. Put the stone in various light sources and see flashes of colors, as from a rainbow. If colours look too uniform or lifeless, the stone could be synthetic.

Examine for Natural Inclusions

Often, opals naturally possess inclusions or minor imperfections formed when the opals are created. In the case of boulder opals, these inclusions can be small cracks, spots, or even ironstone matrix. Synthetic opals do not have any of these natural imperfections.

Hydrophane Test for Ethiopian Opals

Ethiopian opals are hygroscopic. That means it absorbs water. So, if you submerge the Ethiopian opal in water, you can expect it to become more transparent for a little while. Do not test all opals because this may damage some of them.

Obtain Certification

Always source opals from reputable dealers who can give certification that the gemstone is authentic. Then an authorized gemologist decides whether or not the opal is natural or synthetic and any treatments it has.

Buying Tips for Opal Gemstones

In buying an opal gemstone, here are some of the important factors to consider for you to get the best quality of your investment:

Colour and Play-of-Colour

The play-of-colour is the most important aspect when choosing an opal. The more brilliant and intense colors will be, the costlier the gemstone. Black opals with strong flashing red varieties are deemed the most expensive.

Body Tone

Body Tone: This is the background color of an opal. The color can range from a dark, black color to even a light white color. Generally, the deeper the body tone, the more intense the play-of-color and the higher the value of the stone.

Clarity

The clarity of an opal is the measure of how clear or transparent it is. Crystal opals rank at the top in terms of clarity since this means that their play-of-color will be much brighter. 

Size and Carat Weight

Just like in other gemstones, the size and carat weight of an opal can dramatically affect its price. Thus, big opals with vivid color shows would cost more, but smaller ones with strong play-of-color could also be quite pricey.

Care for Your Opal Gemstone

An opal is a delicate gemstone and requires special care to maintain its beauty, not to mention prevent damage. Here are some ideas on caring for your opal gemstone:

Do Not Expose to Heat and Dryness

Opals being hygroscopic are prone to thermal and moisture alterations. This will cause cracking or crazing when the stone’s water content varies too rapidly under extreme heat or dry conditions. In storing, it is best kept in a cool, moist surrounding by covering it in a moist cloth.

Handle with Care

Opals are relatively soft gemstones and carry a 5.5-6.5 rating on the Mohs hardness scale. Avoid wearing opal jewelry during activities that might subject the stone to impact or abrasion.

Mild Cleaning

You can clean your opal by gently wiping it with a soft cloth and warm, soapy water. Avoid cleaning your opal with harsh chemicals, ultrasonic cleaners, or steam cleaning since such methods are likely to hurt your stone.

Conclusion

Opal gemstones are some of the most interesting creations of nature, owning incredible play-of-color and a long history. Be it the mystery of black opals or the fiery brilliance of Mexican fire opals, or even to the otherworldly beauty of Ethiopian opals, all come as unique mixes of visual and spiritual allure. Then, when purchasing an opal, consider the color, the body tone, and clarity, and acquire from a reputable dealer to ensure that its provenance is confirmed. Good care of your opal gemstone will be treasured to be passed down generations for centuries to come, admiring and in awe of its qualities.
