Pay Close Attention When Buying Diamonds!
Scammers are prevalent in the world, so when purchasing diamond-embedded jewelry, it’s crucial to pay close attention to specific details. One of the first things to consider is the diamond’s official certificate, which serves as evidence of its legitimacy.
A diamond certificate is a document that records essential information about a diamond, such as the date and time of discovery, weight, and depth at which it was found. Once these details are documented, diamonds are placed in special containers and shipped to designated locations worldwide, including renowned diamond-manufacturing countries like India and China. Thousands of dedicated employees work diligently to clean and shape the diamonds before they are sent to jewelry shops.
Diamonds that pass the necessary examinations are then distributed to jewelry shops worldwide through main diamond-trading companies like De Beers, which governs the global diamond supply and prices. While there is a slim possibility of major disruptions in the diamond industry, as long as no significant problems arise, there should be a steady and consistent supply of diamonds.
Understanding the importance of the official diamond certificate, it is essential to examine this document when purchasing a diamond. However, it’s worth noting that certificates can be tampered with. Fortunately, there are other ways to verify the authenticity of a diamond.
Let’s explore some reliable methods:
- Fog Test:
This test can be performed by anyone, regardless of their knowledge of diamonds. Hold the diamond between two fingers, leaving space above and below it. Breathe directly on the diamond, and observe if the fog disappears immediately. If it does, the diamond is genuine. If the fog lingers for several seconds, the stone is likely not a diamond. For comparison, you can also perform the test on a fake diamond, which will retain the fog for a longer duration. - Water Test:
This test can be conducted at home or at a jewelry shop with a transparent glass and water. Fill the glass with water, leaving some space at the top. Drop the diamond into the glass and observe its behavior. If the diamond sinks to the bottom, it is genuine. Fake diamonds tend to float or remain closer to the surface due to their lower density. - Diamond Tester:
For added assurance, you can use a diamond tester. These handheld devices analyze a diamond’s heat conductivity and emit a steady beep for genuine diamonds. Fake diamonds do not elicit a beep. Diamond testers are reliable tools for consumers to test diamonds before making a purchase.
It’s important to note that alternative tests, such as subjecting the diamond to heat or hitting it with a hammer, should be avoided as they can damage the diamond’s appearance and decrease its value.
By utilizing these recommended tests, you can confidently assess the authenticity of a diamond without compromising its value or beauty.

To Sum Up
No matter when or where you purchase your diamonds, it’s crucial to allocate some time to test their authenticity. Fake diamonds have become increasingly prevalent nowadays. To learn how to determine if a diamond is real, it is advisable to start by understanding how to interpret the official certificate. While a diamond with proper documentation is likely genuine, it is still worth reviewing the certificate to gather information about the diamond’s origin and quality.
In the absence of a certificate, you can conduct one of the following tests to assess if the diamond is genuine:
- Fog Test
- Water Test
- Diamond Tester
Although there are alternative tests available, we recommend refraining from them as they can potentially harm your diamonds. It is essential to keep your precious gems safe and rely on scientifically proven and accurate testing methods.
