How to Spot a Fake Diamond: Buyer’s Awareness Guide
Understanding the Basics: What is a Diamond?
Diamonds are one of the most coveted and valuable gemstones in the world, often symbolizing love, commitment, and luxury. Whether you’re buying a diamond engagement ring or simply investing in a beautiful piece of jewelry, it’s important to ensure the stone you’re purchasing is genuine. Unfortunately, the market is flooded with counterfeit diamonds, making it essential for buyers to be vigilant and knowledgeable.
In this comprehensive guide, we will walk you through various methods to spot a fake diamond, helping you make an informed purchase and avoid falling prey to scams. From understanding the differences between lab-grown diamonds and natural diamonds to using simple tricks to test a diamond’s authenticity, we’ve got you covered!
Understanding the Basics: What is a Diamond?
Before you can effectively spot a fake diamond, it’s important to understand what a real diamond is and how it differs from other materials. A diamond is a naturally occurring crystalline form of carbon, known for its exceptional hardness and brilliance. It is graded based on the Four Cs: Carat, Cut, Color, and Clarity.
Knowing these characteristics is the first step in identifying a genuine diamond. A real diamond is a symbol of rarity, beauty, and timeless value. However, there are several fake or imitated diamonds in the market, and they can be very convincing if you aren’t careful.
In Mangalore, this tradition has continued for centuries. With a mix of devotion and elegance, the jewellery became an integral part of religious festivities and weddings, forming a vital link between the spiritual and the cultural fabric of the region.
1. The Fog Test: A Simple Method to Check Diamond Authenticity
One of the easiest ways to test if a diamond is real or fake is through the fog test. This method works because diamonds disperse heat very efficiently, unlike fake diamonds, which trap heat.
How to do the Fog Test:
Hold the diamond between two fingers.
Exhale onto the diamond, creating a light fog (similar to how your glasses fog up in the winter).
If the diamond is real, the fog will disappear almost immediately. If it’s a fake diamond, the fog will linger for a few seconds.
This test is based on the principle that diamonds have excellent thermal conductivity, allowing them to clear up fog much faster than synthetic stones or imitations.
2. The Water Test: A Quick Trick to Spot a Fake Diamond
Another simple test you can perform at home to determine if your diamond is real or not is the water test.
How to do the Water Test:
Fill a glass with water.
Drop the diamond into the glass.
A real diamond will sink to the bottom quickly. Fake diamonds or imitations will float or hover halfway through the water.
The reason this works is because diamonds are dense and have a higher specific gravity than most other materials used to create fake diamonds. The sinking behavior is a clear sign of authenticity.
The jewellery typically features motifs such as peacocks, elephants, flowers, and deities. The emphasis is on intricate detailing, which is why it takes skilled artisans many hours to craft each piece. In Mangalore, jewellery houses such as S.L. Shet Diamond House are well-known for offering high-quality temple jewellery that embodies the skill and artistry that this tradition demands.
3. Check the Diamond’s Setting and Mounting
A genuine diamond is typically set in high-quality metals like platinum, gold, or white gold. Fake diamonds, on the other hand, might be set in cheaper, more easily worn-out metals like sterling silver or brass.
Things to Look For:
Clarity of the setting: A high-quality diamond will have a well-crafted setting with no signs of wear or poor finishing.
Metal quality: A reputable jeweler will use precious metals to hold the diamond. Look for a stamp or mark that indicates the metal type (like “14K” for gold or “Pt” for platinum).
When in doubt, ask for a certification or documentation that authenticates the metal and the diamond itself.
In Mangalore, temple jewellery is often worn by brides on their wedding day, adding a regal touch to their traditional outfits. It is also popularly worn during festivals like Makar Sankranti, Ugadi, and Navratri, when people celebrate their rich cultural heritage.
4. The Diamond’s Shape and Cut
The cut of a diamond is crucial in determining its brilliance and sparkle. A real diamond will have sharp, well-defined facets that catch and reflect light in stunning ways. Fake diamonds, however, may appear cloudy or lack the same fire and brilliance.
What to Look For:
Symmetry: A real diamond cut is precise and symmetrical. If you notice uneven or imperfect angles, it might be a sign of a fake.
Brilliance: Hold the diamond under a light source and observe the way it reflects light. A real diamond will sparkle and show a mix of white and colored light (the “fire”). Fake diamonds may appear less vibrant.

5. Use a Loupe or Magnifying Glass to Inspect the Diamond
A jeweler’s loupe or magnifying glass can be a helpful tool in spotting a fake diamond. Under magnification, you can inspect a diamond’s clarity and internal characteristics, which are difficult to replicate in fake diamonds.
What to Look For:
Inclusions and flaws: Real diamonds often have natural inclusions (tiny imperfections) inside the stone, while fake diamonds typically lack these internal characteristics.
Laser engraving: Some diamonds come with a microscopic engraving on their girdle (edge), marking their authenticity. It’s usually a certification number or logo. Look for a small marking with a jeweler’s loupe.
The gold jewellery worn by grandmothers and mothers is often seen on younger generations, preserving the legacy and cultural richness of the community. Temple jewellery’s timelessness makes it an invaluable treasure in Mangalore, where tradition is highly valued.
6. The Refractive Index Test: How to Spot Fake Diamonds
Diamonds are known for their high refractive index, which means they bend and reflect light in a way that other stones cannot replicate. To test this, you’ll need a special tool, called a refractometer, which most jewelers will have.
How to use a Refractometer:
A refractometer measures the angle at which light passes through the diamond. Real diamonds have a high refractive index, while fake diamonds or imitations have a much lower one.
This is a more technical test, and while it’s not something most buyers will have on hand, it’s a helpful tool for jewelers when confirming the authenticity of a stone.
7. Certification and Documentation
One of the most reliable ways to confirm the authenticity of a diamond is to ask for a diamond certificate. Reputable diamonds, especially those sold in places like S.L. Shet Diamond House in Mangalore, will have certificates issued by gemological organizations such as the GIA (Gemological Institute of America) or IGI (International Gemological Institute).
What the Certificate Includes:
Carat weight
Cut grade
Clarity grade
Color grade
Diamond’s origin (natural or lab-grown)
When buying a diamond, always ask for a certification to ensure its authenticity and value.
8. The Cost Factor: Authentic Diamonds Are Expensive
Lastly, the price can be a big giveaway when it comes to spotting fake diamonds. Real diamonds are expensive due to the rarity of the material, intricate cutting process, and high demand. If the diamond you’re eyeing seems too good to be true, it probably is.
Fake diamonds or imitations are typically far less expensive than natural diamonds. While price alone shouldn’t be your sole determinant, it’s a good indicator when combined with the other tests mentioned above.
