Opal Myths, Meaning, and Significance

Opal gemstones are one of the world’s most unique and mysterious precious stones, so it’s easy to understand why their history is full of myths and legends.

Opal myths and legends

Opal was once a highly prized gemstone by the ancient Romans – they believed it represented the combined beauty of all precious gems. The ancient Greeks believed opal came from the tears of Zeus, the God of lightning, after his defeat of the Titans. Similarly, Arabic legends say opal fell from the sky amid flashes of lightning. Sometimes cultures credited opal with supernatural origins and powers. For example, ancient Greeks believed opals gave their owners protection from disease, particularly skin disorders and eye ailments.

Perhaps one of the most interesting legends is that of the Indian Goddess of the Rainbow. It is said she was so beautiful that she became overwhelmed with the attention of male suitors. In a desperate act of escape, she turned herself into a stunning rainbow-colored opal. 

Today, opal remains prized for its vibrance and unique play-of-color (the ability to diffract light into flashes of rainbow color). The finest opals display all the colors of the spectrum over the stone’s entire surface.

Are opals bad luck?

You may have heard that wearing opals will bring you bad luck, but that’s simply untrue. Throughout history, opals were thought to bring the wearer good luck. In fact, ancient Romans believed opals were one of the luckiest gemstones in the world and considered them symbols of hope, fidelity and purity. During the mid 1300s, opals became associated with the Black Plague due to a rumor that a victim was wearing an opal that went dull after she passed. It’s more likely, however, that the opal simply deteriorated from neglect. Opals are softer and more porous than other gems but can last a lifetime with the proper opal care and attention.

They had another brief fall from grace after an 1829 novel written by Sir Walter Scott entitled Anne of Geierstein. At that time, it was customary for authors to release one chapter at a time. It was a story of a woman who is falsely accused of being a demoness and dies soon after a drop of holy water accidentally falls upon her opal, destroying its color. The public, having likely not read the entire book to learn she was actually poisoned, misinterpreted this as a warning from the author that opals may bring misfortune to whoever wears them. It was nearly 59 years before the reputation of opals was restored with the discovery of a breathtaking black opal found in South Wales, Australia.

Black Opal Broad Color Spectrum

Black opals are exceptionally rare and valuable, due to their dark body tone and the resulting vibrant play of color. To date, they have only been found in Australia however a similar aesthetic is sometimes fashioned using a doublet or triplet technique.  While also beautiful, doublets and triplets require different care than solid opals, given their layered formation.

How Do You Properly Care for Opal?

Many people are drawn to the mystical flash of color for which opal rings are so well-known. They’re deliciously complex, yet surprisingly neutral which makes them the perfect companion for many other gemstones.

Australian opal has become more popular and has increased in value over the past decade. In fact, it is one of the most popular colored gemstones today.

Whether you own a solid opal, doublet, or triplet, or are ready to shop for one, it’s important to learn how to take care of them so you can enjoy them for years to come. Opals are softer and more porous than other gems, but they can last a lifetime with the proper opal care and attention. 

Solid opal care guidelines

Opal is approximately the same hardness as glass, so it is important to treat it carefully to avoid damaging it. Here are a few important opal care do’s and don’ts:


  • Gently clean your solid opal jewelry with mild detergent, warm water, and a soft toothbrush or cloth.
  • Remove your opal rings before applying any product; particularly those that may contain acid or alcohol (hair products, perfumes, hand sanitizers, lotions, etc.)
  • Visit an experienced opal cutter if you have an opal that has become dull or scratched. They will be able to properly polish and restore your precious gemstone.
  • Store your opal jewelry in a padded cloth bag when you aren’t wearing it. If you have individual jewelry boxes for your pieces, place it inside for added protection. For longer storage periods, place it in a cotton or wool cloth with a few drops of water and then put it into a sealed plastic bag. This will help prevent water from coming out of the stone.
  • Follow a “last on, first off” rule to keep your opal rings vibrant for years to come. Opal should be the last thing you put on before an event or occasion and the first thing you take off and store appropriately when you return home.

  • Wear your opal ring if there is any chance it could get scratched, damaged or broken. (Avoid wearing opal jewelry while exercising, working in the garden, doing the dishes, bathing, moving furniture, etc.)
  • Fully immerse your doublet or triplet opal rings, earrings, or necklaces in water. This will help keep these precious gemstones healthy and vibrant.
  • Leave your opal in a place where it could be subject to very high temperatures or low humidity (e.g., boiling water or zero humidity bank vaults).
  • Use bleach, chemicals, or other harsh cleansers (including ultrasonic cleaners).

Opal doublet and triplet care guidelines

Opal care for doublets or triplets is a bit different from caring for solid opals. Opal doublets and triplets consist of multiple layers glued together. For this reason, prolonged exposure to water will eventually cause lifting between the layers allowing water to seep in. If this happens, your doublet or triplet will take on a ‘foggy’ or grey appearance and will likely result in permanent damage. Do not immerse your doublet or triplet opals in water for any significant length of time.

What's the Difference Between Opal Doublets, Opal Triplets, and Solid Opals?

Opals come in three different categories: doublets, triplets, and solid opals. Opal doublets and triplets are a beautiful and more affordable alternative to solid opals, but it is important to understand the differences between them to determine which option is most suitable to your lifestyle. Opal doublets and triplets are layered opals designed to enhance the appearance and perceived value of a thin or lighter piece of opal by gluing it to a dark backing, amplifying its unique play of color.

Identifying opal doublets, opal triplets, and solid opals

Let’s take a closer look at each type of opal and how to identify them:

Opal doublets

An opal doublet is a type of assembled gemstone composed of two layers: a piece of clear or translucent opal and, most often, a piece of black or dark potch (common) opal. The dark backing may also be black industrial glass, hard plastic, brown ironstone, or vitrolite. A doublet can be identified by looking at its side or edges. It will have a very clean, straight, and visible seam where the opal was glued to the black backing, whereas the edge around a solid opal will have a more organic, jagged delineation between colored precious opal and host rock. Doublets are commonly used to imitate a solid black opal because the black backing shows through the clear, solid opal resulting in darker and more vibrant colors.

As you can see from these images, unless you know exactly what the difference is, a solid opal can be easily mistaken for a doublet and vice versa. In fact, this happened to one of our clients. She sent us what she believed was an opal doublet that her dad had gifted her and requested we transform it into a necklace. However, upon closer inspection, we were delighted to share with her that her stone (2nd image) was actually a stunning, solid Boulder Opal. She was thrilled (as were we!) and she now adores the one-of-a-kind, gold opal necklace we created for her from her breathtaking and sentimental blue opal.

Opal triplets

An opal triplet is similar to an opal doublet in that it is also a thin slice of opal that’s been enhanced by a darker host rock; however, the solid opal is then magnified with a domed quartz or glass topper. This creates three layers to this type of opal – hence the name ‘triplet.’  The black backing does an excellent job of illuminating the play of color on the opal layer, which can really make the piece of jewelry stand out. Combining this with a glass topper not only protects the opal, but magnifies the intensity of the color and pattern, which can greatly enhance the overall appearance. Moreover, because the topper is made of synthetic materials, triplets have the benefit of a buffering layer from impact.

Here are three signs of an opal triplet:

  1. A glue line where the solid opal meets the base.
  2. A very thin layer of color sandwiched between a dark-colored potch opal and a dome of quartz or glass.
  3. The opal top looks glassy, and the color does not travel to the top of the gemstone.

Solid opals

Natural solid opals are the most valuable because they are cut from only the natural stone without any treatment or enhancement. There have not been any man-made clear tops or backing glued to them. While all opal should be handled with care, solid opals are generally more durable than doublets or triplets because they are composed of one solid piece of opal, rather than a thin layer of natural opal adhered to additional materials.  Three of the most predominant types of solid opal include light and crystal opal, Boulder opal, and Black opal.

How to care for opal doublets and opal triplets

Opal doublets and triplets can be beautiful and more cost-effective alternatives to solid opal gemstones. However, it is important to understand how to care for them to avoid damage. Doublets and triplets are made of multiple layers that have been glued together, so exposure to water will eventually cause lifting between the layers and water damage. If this happens, they will start to appear ‘foggy’ or grey and the layers can separate completely.  While opal doublets can be just as striking in appearance as solid opals, a doublet can also be more susceptible to damage, given its very thin layer of opal atop the potch. This is something to take into consideration when deciding whether to opt for a doublet or a solid opal in your opal jewelry.

To care for these pieces, doublets and triplets may be wiped with a soft, damp cloth and mild detergent, but should never be soaked or submerged in water. You should also avoid bleach, chemicals, cleaners, and ultrasonic cleaners, avoid blunt force and remove these pieces before any rigorous activity.  While chemical exposures and blunt force should also be avoided with solid Australian Opals, solids should not be damaged by immersion in water.

What’s the Difference Between a Precious and Non-Precious Opal?

The word opal notoriously conjures images of rainbows and colorful flashes. But not all opal aligns with this visual; it speaks to precious opal, but largely neglects non-precious opal which accounts for a great deal of the opal recovered from mining.

Opal is formed from a solution of silicon dioxide and water. As rainwater trickles down through the fissures in the earth it picks up silica from sandstone along the way. Next, the now silica-rich solution settles into cracks and voids of all sizes. Over a long period of time the water evaporates and leaves behind a beautiful silica deposit we call opal.

Opal is composed of uniform spheres of silica, which assemble in a grid-like structure. The spaces between these spheres contain the silica solution. As light passes through the spheres and into this silica solution, it is diffracted, producing an alluring rainbow of vibrant hues.

Both precious and non-precious opal is mined from these crevices and while both are quite beautiful, they are very different from one another.

Precious vs. non-precious opal

Precious opal is the term used for any opal that exhibits a “play-of-color” or iridescence. This means as light illuminates the inner contours of the opal, it’s diffused or dispersed throughout the silica spheres to create a brilliant prism of spectacular color. Other examples of things that exhibit this play-of-color or iridescence are soap bubbles, feathers, butterfly wings, and seashell nacre. 

If you’ve been following NIXIN Jewelry for a while, you may recall our email about the Papilio Blumei Ring, inspired by an Indonesian butterfly, that described this precise effect. If you'd like to join our mailing list, add your email address to the bottom of our homepage.

Non-precious opal, also called common or “potch” opal, does not exhibit a play-of-color like precious opal and is often milky in appearance. Common opal is typically gray, black, white, or amber in color, but it also occurs naturally in a variety of beautiful colors including a range of lovely pastels. Non-precious opal is found in the same environments as precious opal but is considered less valuable. Depending on the appearance of the potch, a miner or cutter may opt to use it, given the beautifully unique patterns that can result when potch is woven into precious opal, as in the example below.

How is opal valued?

It is notoriously difficult to value opals because there are so many factors to consider, and they vary so widely in appearance and quality. There are three main aspects that determine whether an opal is precious (highly valuable) or non-precious (less valuable):

  • Color
    Body tone (color) is one of the most important factors in the classification and valuation of opals and refers to its overall background or underlying color. Black opal, white opal, crystal opal, boulder opal and matrix opal are all varieties of precious opal, which is also called noble opal. Generally, opals with darker backgrounds are more valuable than those with a lighter background because stones with darker backgrounds offer a more vibrant display or play of colors. Under the right circumstances, the color red, a rarer find, can also drive up the value of an opal.
  • Pattern
    Distinct color that is displayed in a pattern or pattern segments further determines the quality of an opal. Excellent pattern types include uniform color segments, straight edges, large sections of color in a random pattern, parallel cascading lines of narrow, rolling color or thin strips of overlapping color that may or may not resemble an object, landscape, animal, or person.
  • Clarity
    The size and quantity of inclusions (small imperfections) can detract from the value of an opal. Imperfections may include cracks, grains of sand or other minerals, potch lines, webbing (gray lines), and windows (sections without color).

Sometimes, potch can even “paint” incredible pictures within an otherwise precious opal, blurring the lines between what’s deemed valuable by traditional industry standards and what is viewed as a treasure in the eye of the beholder.  Here at NIXIN, we readily embrace a combination of qualities in these sublime stones, as long as the final result is uniquely beautiful.
