Unmasking Fake Diamonds: Expert Guide to Buying Authentic Diamond Jewellery

In the glittering world of gemstones, diamonds reign supreme. But it’s not always easy to distinguish real diamonds from the fakes. With the rise in sophisticated counterfeits, it’s more vital than ever to know how to spot fake diamond jewellery.

Experts in the field have shared their top tips on how to identify genuine diamonds. They’ll guide you through the process, helping you make informed decisions when purchasing diamond jewellery. So, whether you’re a seasoned collector or a newbie, these expert tips will be invaluable.

Remember, knowledge is power. The more you know about diamonds, the less likely you’ll fall for a counterfeit. So, let’s jump into the world of diamonds, and learn how to separate the real from the fake.

Understanding the Basics of Diamond Quality

If you’re to separate the real diamonds from the dupes, it’s crucial to understand the key elements that contribute to a diamond’s quality. Diamond quality revolves around the Four Cs: Carat, Cut, Clarity, and Colour.

Carat reflects a diamond’s size, where one carat equals 200 milligrams. It’s worth noting but that bigger doesn’t always mean better. Other aspects play a vital part in determining a diamond’s value. For example, a smaller diamond with excellent cut and clarity could arguably be worth more than a larger diamond with significant imperfections.

The Cut of a diamond influences its sparkle and brilliance. A well-cut diamond reflects light beautifully and gives the unmistakable fire and radiance that diamonds are renowned for.

Clarity refers to the presence of imperfections, both inside (inclusions) and on the surface (blemishes) of the diamond. The fewer the flaws, the higher the quality.

The final C, Colour, assesses the presence of any colour in a diamond. In general, the best diamonds are totally colourless, ranking D on the industry colour scale, which goes up to Z.

By understanding these basics, anyone can evaluate a diamond’s quality effectively. It may take a bit of practice, but once mastered, it would be a big step towards separating genuine diamonds from fakes.

Examining Diamond Clarity and Cut

An indisputable factor for evaluating a diamond’s quality is its clarity. Clarity refers to the degree to which internal and external imperfections, known as inclusions and blemishes, disrupt the passage of light through the diamond. Essentially, the fewer these imperfections, the greater the clarity, and so, the higher the diamond’s value. But it’s worth noting that many of these imperfections are microscopic and can’t impact the diamond’s beauty to the naked eye.

Understanding a diamond’s cut is as significant as understanding its clarity. While people often mistake the cut to mean the diamond’s shape, it primarily refers to how effectively the diamond interacts with light. Elements such as symmetry, proportions, and polish determine the brilliance, fire, and scintillation of a diamond. Hence, a well-cut diamond will reflect light beautifully, resulting in a stunning piece of jewellery.

To put it simply, when looking at diamonds, don’t just focus on size or weight, give equal importance to clarity and cut. These two factors play critical roles in determining a diamond’s quality and hence its price.

It’s all about understanding the basics and making an informed judgement. So, consider these tips from the experts next time when making a diamond purchase. Beware not only of fakes but also substandard quality diamonds.

Using a Diamond Tester: How it Works

In the mission to prevent the purchase of substandard or fraudulent stone, a diamond tester plays an instrumental role. To understand how it works, it’s pivotal to note: a diamond tester measures heat conductivity.

Following the principles of thermodynamics, genuine diamonds, characterised by their atom-specific structure, conduct heat differently from their imitation counterparts. A diamond tester utilises this key difference to separate real gems from the fakes, providing a quick and straightforward way to ensure your potential purchase is legitimate.

There are two common types of diamond testers: thermal and electrical conductivity testers. A thermal tester gauges how efficiently a stone conducts heat, while an electrical tester measures electricity conduction.

Here’s a brief on how each works:

  • Thermal Tester: It investigates a stone’s rate of heat loss. If the tested gemstone loses heat quickly, it’s likely not a diamond. In contrast, diamonds retain heat for a significant length of time.
  • Electrical Conductivity Tester: Diamonds and their synthetic counterparts like Moissanites exhibit different electrical conductivities. An electrical tester exploits this discrepancy to confirm the stone’s authenticity.

With a practical understanding of diamond testers, potential buyers can make more informed decisions and ensure they get value for their money.

Top Techniques to Identify Fake Diamond Jewellery

There isn’t just one quick and easy way to spot a fake diamond. Experience and understanding play a key role in differentiating between a real diamond and a counterfeit.

One such essential tool for diamond evaluation is the loupe. A loupe’s magnification reveals minute details in the structure of the stone which may not be visible to the naked eye. Experienced jewellers or gemologists utilise this tool, inspecting the stone for natural inclusions or flaws expected in a genuine diamond.

Certain gems mimic diamonds quite well under regular light. But, they exhibit stark contrast when viewed under UV light. A glowing blue fluorescence is often indicative of a real diamond; although it isn’t an irrefutable sign, it’s a solid starting point.

A fog test involves breathing onto the diamond, creating a layer of condensation. Real diamonds, owning up to their good heat dispersion properties, don’t hold onto the fog for more than a couple of seconds.

Finally, as mentioned before, diamond testers (both thermal and electrical) provide sound means to authenticate diamonds. By measuring heat or electrical conductivity, they make use of the unique atomic structure inherent to diamonds securing a buyer’s investment.

With a blend of professional tools, practical experiments and a keen eye, one can confidently discern a real diamond from the rest – asserting its worth every step of the way. Ascertaining diamond authenticity isn’t about hunting the perfect diamond; it’s about preventing oneself from falling into the trap of deceptive sparkle.

Expert Advice on Purchasing Authentic Diamond Pieces

When buying diamond jewellery, caution and research are keys. Knowledge is power and it serves as an effective deterrent against fake diamond dupes. Experts suggest starting with basics. Understanding important diamond characteristics, known as the four C’s: Cut, Carat, Clarity, and Colour, is essential. These criteria significantly influence both a diamond’s appeal and its price.

Experience jewellers often recommend purchasing diamonds from reputable sellers. Well-established jewellers usually have rigorous processes to ensure they’re selling only authentic diamonds. These professionals utilise both manual inspections and technical tools like Diamondite KS900, which analyses and verifies a diamond’s heat dispersion properties.

Another point of consideration is the vendor’s return policy. Sellers confident in their product typically offer a favourable return policy, allowing customers an opportunity to have their purchase independently evaluated.

Certification, from organisations such as the Gemological Institute of America (GIA) or the American Gem Society (AGS), provides another layer of assurance. These certificates validate that the diamond has undergone unbiased, professional evaluation.

In the quest for a real diamond, there is no substitute for due diligence. An informed buyer can confidently navigate the dazzling world of diamond jewellery, effectively differentiating the authentic sparkle from deceptive twinkles.


So, there you have it. The world of diamond jewellery isn’t as daunting as it might first appear. With a bit of caution and the right knowledge, anyone can find a true gem. Remember the four C’s, always buy from trusted sellers and don’t forget to use verification tools like Diamondite KS900. Don’t shy away from asking for certifications from organisations like GIA or AGS. And of course, always check the return policy. Buying diamond jewellery should be a joy, not a chore. With these expert tips, you’re now equipped to spot the real from the fake. Happy diamond hunting!

What factors should I consider while purchasing diamond jewellery?

The key factors you should consider include the four C’s – Cut, Carat, Clarity, and Colour of the diamond. In addition, ensure you’re purchasing from a reputable seller, and check their return policy.
