To tell if an opal is real, look for an irregular, organic "play-of-color" that shifts with angle, unique patterns (not uniform), and imperfections like slight cracks or uneven surfaces, which fakes often lack, featuring flat backs, perfect columns, or "lizard skin" textures instead. Use magnification to spot columnar structures in synthetics, check the base for flat glue lines (doublets/triplets), and note that real opals are generally harder and don't easily absorb water like some fakes.
Check if the 'join' between the opal and the backing is perfectly flat, creating a straight line around it. Most real solid opals have a little quirk in this zone – they're curvy or bumpy, showing off their natural formation.
When identifying a genuine opal, particularly a precious Australian stone, look for:
One of the characteristics of Hydrophane Opals are that when submerged in liquid, its appearance can change. If Hydrophane Opal is soaked in water, the water is absorbed into the Opal. As a result, any play of colour(fire) will seem to have disappeared. Colour will normally return once the Opals dries out.
The Back of the Opal:
A Doublet is a little harder to spot as the backing is more often a piece of natural potch (black, colourless opal) or ironstone (boulder opal host rock). The best way to tell if it is a doublet is by checking if the join between the opal and the backing is perfectly flat or curved and bumpy.
Column-Like Colour Structure – Check the sides of the opal. Synthetic opals will have a neatly lined column structure with a uniform, repeated pattern. A real opal will appear solid when viewed from the side. Porosity & Weight – Synthetic opals are more porous and have a lower density, making them feel lighter.
Water Test: Genuine opals don't turn transparent when soaked. If yours does, it might be a doublet. Light Test: When you shine a light on a real opal, the refraction will be different from that of its imitations.
Prices range from $10 to $20,000 per carat based on their exceptional color and rarity. In contrast, white opals, known for their milky and pearly white appearance, often sell at lower prices due to their more common nature.
People involved in manual labor, sports, or with very active lifestyles should avoid constant opal ring wear due to its softness (Mohs 5.5-6.5), risking scratches and cracks, while some astrological beliefs suggest Aries, Leo, Scorpio, and Cancer signs, or those with incompatible planets, should also be cautious. Otherwise, opals are generally fine for anyone to wear, but require careful handling and protective settings like bezels.
To charge the Opal stone, you need to use a simple yet effective ritual. Wear the Opal ring on a Friday morning, but before this, soak it in raw cow's milk mixed with Ganga Jal and a dash of honey for 10 minutes. This cleanses the gemstone. Then, wash it with pure water and dry it with a cotton cloth.
Many specimens of opal display fluorescence under shortwave (100nm - 280nm wavelength) ultraviolet light. A smaller number will display fluorescence under a longwave (315nm - 400nm wavelength) ultraviolet lamp. Some specimens do not show noticeable fluorescence at all.
Identifying Raw Opal
Look for the distinctive play of colors, known as “play-of-color.” Opals can exhibit flashes of various hues when viewed from different angles. Raw Opals are typically not completely transparent. They often have some form of host rock left on them. Raw opals often have a rough, unpolished surface.
To clarify again, Oparex is a plastic material with some color change effect. Glass Opalite is a commonly known imitation opal. It does not show any play of color and is simulating common opal. It is merely glass.
Limited Supply: Black opals are incredibly rare, with the majority of them coming from Lightning Ridge, Australia. The limited supply ensures their long-term value. Historical Performance: Over the years, black opals have demonstrated consistent value appreciation, making them a reliable investment choice.
There are two broad classes of opal: precious and common. Precious opal displays play-of-color, common opal does not. Play-of-color occurs in precious opal because it's made up of sub-microscopic spheres stacked in a grid-like pattern—like layers of Ping-Pong balls in a box.
If the opal is left in a hot, humid place for a long time, it will most likely change color and become cloudy. This may also happen due to severely low temperatures. That is why it is important to keep an eye on the temperature in the room and remove the ring or other jewelry with opal when you are sick.
Wearing opal signifies hope, creativity, purity, and emotional healing, symbolizing transformation and amplifying inner feelings, with ancient beliefs linking it to good fortune, foresight, and protection, making it a stone of balance and spiritual connection, often worn for luck or as a talisman of hope.
Best Zodiac Signs for Opal: Taurus (Vrishabha) and Libra (Tula) Taurus and Libra are governed by Venus and that is why these signs are the best solution to who wears opal or not. To these natives, opal stone has an advantage in terms of better relationships, financial well being, beauty, emotional stability.

How to Tell If an Opal Is Real
Yes, Australian opals are very valuable, often commanding high prices due to their rarity, exceptional "play-of-color," and dominance in the global market (over 90% of supply), with prized types like black opal and boulder opal being particularly sought after and sometimes as valuable as diamonds, ranging from hundreds to thousands of dollars per carat.
Synthetic dudhiya pathar or lab-made Opals often show a strong, dull, or sickly green glow under a short-wave UV light. However, this test is not 100% conclusive, as some natural Opals, like certain Ethiopian or Black Opals, may not glow much at all.
There are three main aspects of an opal's quality:
Many people believe solid opals can be damaged by water – however, this only applies to doublets and triplets. Solid opals are fine in water. In fact, most precious opals contain about 5-6% water. As a result, opal may crack if subjected to very dry conditions or rapid changes in temperature.
