Identifying a real gemstone is a challenge, specifically when the Australian gemstone market is flooded with imitations. Have you ever wondered how experts differentiate between a real and fake opal? This guide will offer insights into spotting an authentic gem, specifically focusing on the prized variety from Down Under.
When it comes to gemstones, there’s no doubt that Australian Boulder Opal is a favourite among collectors and jewellers alike. But how can you tell if what you’re holding is the real deal? In the second paragraph, we’ll dive deeper into this question and provide expert tips on identifying the genuine ones.
Understanding the Unique Features of Boulder Opal
One of the first steps in identifying an authentic gemstone is to understand its unique characteristics. This particular variety is known for its vibrant play of colours, varying from deep blues to bright greens and fiery reds. The stone is often found embedded in ironstone, which is a key indicator of its authenticity.
Genuine stones will display a distinct contrast between the opal and the ironstone. The opal will typically form thin veins or patches across the ironstone, creating a striking visual effect that is difficult to replicate in synthetic versions. The way the colours shift and change under different lighting conditions is another hallmark of authenticity.
Examining the Surface and Structure
Another crucial aspect of identifying an authentic gemstone is examining its surface and structure. A genuine one will have a natural, irregular shape with an uneven surface. Unlike synthetic versions, which often appear too perfect, a real stone will display slight imperfections that add to its charm.
The ironstone backing is usually visible on the underside, and the opal itself will have a slightly textured surface. If the stone appears too smooth or uniform, it could be a sign that it’s an imitation. Additionally, the weight of it can be a giveaway; a genuine gem will feel heavier due to the presence of ironstone.
Using a Magnifying Glass to Spot Inclusions
Experts in Australia often use a magnifying glass to examine a stone closely for inclusions. These are tiny impurities or cracks within the stone that are a natural part of its formation. In a genuine stone, these inclusions will be random and irregular, contributing to its unique appearance.
In contrast, synthetic or fake stones often have perfectly uniform inclusions or none at all, which is a clear indication that they are not real. By utilising a magnifying glass, you can get a closer look at the stone’s internal structure. As such, you can spot these tell-tale signs of authenticity.
Testing with UV Light
One of the most effective methods for identifying a genuine gemstone is by using UV light. When exposed to ultraviolet light, real stones will exhibit a natural fluorescence that is absent in synthetic versions. This glow is a result of the stone’s unique composition and cannot be easily replicated in fakes.
To conduct this test, simply place the stone under a UV lamp and observe its reaction. If it glows with a soft, natural light, it’s likely to be real. However, if the stone remains dull or displays an unnatural brightness, it’s probably not genuine.
Consulting a Professional for an Expert Opinion
The tips mentioned above can help you identify an authentic gemstone. That said, consulting a professional in Australia is always a wise decision. Gemologists and jewellers have the tools and expertise to conduct thorough tests and provide a definitive answer.
Professionals can perform advanced tests, such as spectroscopy or specific gravity measurements, which are not easily done at home. Additionally, they can provide certification that guarantees the authenticity of the stone, giving you peace of mind.
Identifying a genuine Australian Boulder Opal needs a keen eye and knowledge of its unique features. Knowing what to look for can make all the difference when selecting this treasured gemstone. With these expert tips, you can confidently assess the authenticity of your stone and enjoy its natural beauty, knowing that it is the real deal.
