Opals are delicate gemstones that require soft handling. Clean your opal using lukewarm water, mild soap, and a soft brush or cloth. Avoid harsh cleaning agents, ultrasonic cleaners, or abrasive tools, as opals can easily scratch and absorb liquids. Gentle cleaning helps maintain their natural brilliance and vibrant play of colours.

Because opals naturally contain water, they are sensitive to temperature changes. Keep your opal jewellery away from direct sunlight, hot water, and heat sources, as extreme temperatures can cause cracks or dullness. Maintaining a stable, cool environment helps preserve the gem’s beauty and structure.

Check your opal jewellery regularly to ensure the stone remains secure and undamaged. If you notice loose prongs or minor wear, have a professional jeweler inspect and repair it promptly. Routine maintenance ensures your opal retains its charm and durability for years to come.

Store your opal separately in a soft, padded box or fabric pouch to prevent scratches or damage from harder gemstones. Avoid dry or airtight storage; a slightly humid environment helps maintain the stone’s natural moisture. Proper storage safeguards your opal’s delicate surface and radiant appearance.

Opals are mined in Australia, Ethiopia, Mexico, Brazil, Sudan, Hungary, and the USA. Among these, Australian Opals are the most prized for their vivid fire and durability, followed by Ethiopian and Mexican Opals, which often show warm, translucent hues.

Colour plays a major role in determining an Opal’s worth. White Opals with fire are highly valued for astrological benefits, while Black, Blue, and Green Opals are admired for their vibrant play-of-colour. Stones with balanced hues and intense brightness command higher prices.

Clarity depends on transparency and visible inclusions. High-quality Opals have minimal sand spots, webbing, or cracks. Crystal Opals are valued for their transparency, whereas White and Boulder Opals are preferred with opaque, flawless surfaces.

The play-of-colour or fire defines a precious Opal. The brighter and more vivid the fire, the higher the gemstone’s price. Dull or faint fire reduces its value, while common Opals (without fire) are more affordable but hold limited astrological energy.

Opals are usually cut into smooth oval or round cabochons. Stones with balanced domes reflect light beautifully from all angles. Avoid overly flat or steep domes, as they can be more prone to damage when set in jewellery.

The arrangement of colours, or “fire pattern,” significantly affects pricing. Opals displaying broad, bold flashes are rarer and more expensive than those with small pinfire patterns.

Determining the authenticity of an Opal gemstone can be challenging, especially when buying online. Natural, untreated Opals are more valuable—both astrologically and aesthetically—than heat-treated or synthetic ones. Understanding the key differences helps ensure you make an informed and genuine purchase.

Lab-created Opals are often used in inexpensive jewellery, especially earrings and pendants, but they lack the spiritual and astrological benefits of natural Opals. Natural Opals display a unique, irregular play-of-colour and slight internal patterns, while synthetic Opals often appear too uniform and glossy.

A “treatment” refers to any human-controlled process (beyond cutting and polishing) used to enhance a gemstone’s appearance or durability. While mild treatments are common, heavy chemical or heat enhancements reduce the gem’s natural energy and long-term value.

Always purchase certified gemstones. At Rasikh Gems, each Opal comes with an authentic Gem Lab Certificate, verifying its natural origin, treatment status, and quality parameters. You can cross-check the certificate details directly with the issuing gemological laboratory for added assurance.

Before making your purchase, review a trusted Gemstone Buying Guide to understand quality indicators, origin types, and visual cues of genuine Opals. Choose reputable sellers who offer transparency, certification, and expert guidance—ensuring your Opal is as authentic and powerful as it is beautiful.
