The opal stone is mostly known as the October birthstone but there’s so much more to it. If you wish to learn more about opal, you’re in the right place. In this guide, we discuss opal’s composition, value, uses, symbolism, care tips, and how to distinguish a real opal from a fake one.
What is opal?
Opal is one of the most popular gemstones worldwide. Mineralogically, opal is hydrous silica with a chemical composition of SiO2.nH2O. It’s amorphous, meaning it doesn’t have a crystalline structure and is without definite chemical composition. Due to its amorphous properties, opal is classified as a mineraloid and not a mineral.
While different types of opal exist, it’s broadly classified into two types: precious opal and common opal or “potch.” Precious opal displays the characteristic play-of-color (flash of spectral colors) and is rarer than common opal. Common opal is dull and doesn’t exhibit play-of-color.
The precious opal’s internal structure causes light diffraction, resulting in the play-of-color. The bright rainbow colors, seen by the human eye, will move and change depending on which angle you view the stone.
Some scholars believe that opal gets its name from the Sanskrit word “upala” which means “precious stone” while others say it’s from the Latin word “opalus,” which derives from the Ancient Greek “opallius,” which means “color changing.”
In ancient times, people believed that opal possessed all the properties of gemstones whose colors flicker within it, and thus opal gained its reputation as the “Queen of Gems.”

How can I tell if my opal is real
Besides genuine opal, synthetic opal exists, as well as man-made opals are known as doublets and triplets. Before buying an opal, it’s essential to understand what doublet and triplet mean so you know if your opal is genuine.
A doublet is made of two layers bound together with glue. The first layer is a black backing made from either hard plastic, black industrial glass, brown ironstone, vitrolite, or black potch. The second layer is a thin slice of opal (white or crystal opal). The opal is generally thicker than the opal found in a triplet.
A triplet is made of three layers. The first layer is a black backing, the second layer is a very thin slice of opal in the middle, and the third layer is clear glass and plastic capping or quartz in the shape of a dome.
So how can you tell if your opal is real?
Observe the side of the opal
A genuine opal will not have distinctly visible layers. It may be a doublet or triplet if you notice flat layers on the side. A natural opal will have an uneven join.
Examine the bottom part of the opal
Check the back of the opal. If you notice a gray or black hard-ish coating, it’s probably a triplet, as they are often glued onto vitrolite backing or black plastic glass.
Look at the top of the opal
If the top of the opal looks glassy, it’s most probably a triplet. Triplets are capped with quartz or hard clear plastic, so the top of the opal reflects differently from that of the genuine opal. In addition, if you can see through the top of the opal from a side view, you are most likely looking at a triplet.
Observe the tone of the opal
If the opal is transparent or has a white body tone, it’s most certainly a genuine stone. All doublets and triplets have a dark body tone because they have a black artificial backing.
Look at the pattern
Sometimes, it’s hard to distinguish genuine opals from synthetic ones made in a laboratory. Laboratory-made opals display bright colors in large patches of color. Their pattern is often too perfect and ordered, unlike a genuine opal.

How to care for opal jewelry
Use these tips to care for your opal jewelry:
- Clean the jewelry with a mild detergent in warm water using a soft toothbrush or cloth. Avoid using chemicals and bleach.
- If you want to store it for longer periods, place the gemstone in cotton wool with a few drops of water, then put it in a sealed plastic bag. Opals have 6-10% water content and will dry out and crack if they are in dry storage.

- Store your opal jewelry separately from other pieces to avoid scratches.
