How to Identify Genuine Diamonds: Fake vs real diamond test

Diamonds are one of the most precious gemstones in the world, but the market is also flooded with fake diamonds. In recent times, the topic of fake vs. real diamonds has become a growing concern in Bangladesh. With such a surge in fake diamonds, identifying a genuine one can be challenging.

Whether you're buying a diamond for a special occasion or want to ensure the authenticity of a piece of jewelry, knowing how to differentiate between fake and real diamonds is essential.

This blog will guide you through simple yet effective tests to distinguish a genuine diamond from a fake one.

Universal diamond testing methods

Here we discuss the universal diamond testing methods, I hope this testing process will give you the right guidelines to choose authentic diamond jewelley products in Bangladesh.

1. The Water Test

   One of the simplest tests to check the authenticity of a diamond is the water test. Take a glass with water and drop the diamond into it:

   • Real Diamond: A real diamond has a high density, so it will sink to the bottom.
   • Fake Diamond: A fake or imitation diamond will float or remain suspended in the water.

2. The Fog Test

   Diamonds conduct heat effectively, which makes the fog test another reliable method. Here's how it works:

   • Real Diamond: If you breathe on a real diamond, the fog will disappear almost instantly due to the stone's thermal conductivity.
   • Fake Diamond: A fake diamond will stay foggy for a longer period because it cannot dissipate heat quickly.

3. The Scratch Test

   While this test is less commonly used due to potential damage, it can help:

   • Real Diamond: Diamonds are the hardest naturally occurring material on Earth (Mohs hardness scale 10). They can scratch almost any surface, including glass.
   • Fake Diamond:A fake diamond, like cubic zirconia, will not scratch glass or will do so less effectively.

4. The UV Light Test

   Some diamonds fluoresce under ultraviolet (UV) light:

   • Real Diamond: Many genuine diamonds will emit a blue glow under UV light. However, this does not apply to all real diamonds.
   • Fake Diamond: A fake diamond or imitation stone may not fluoresce or may display different colors like green, yellow, or gray.

5. The Newspaper Test

   Due to their refractive index, real diamonds make it difficult to see through them:

   • Real Diamond: If you place a real diamond over a newspaper, you shouldn't be able to read the letters through the stone.
   • Fake Diamond: An imitation diamond will allow you to see the letters or even clearly read through them.

6. The Heat Test

   Heat is another crucial way to test diamond authenticity:

   • Real Diamond: A genuine diamond can withstand extreme heat. Hold the diamond with tweezers, heat it for about 40 seconds, and then drop it in cold water. A real diamond will not break or crack.
   • Fake Diamond: Fake diamonds, made of weaker materials, may crack or shatter from thermal shock.

7. Using a Loupe

   Jewelry experts often use a loupe to inspect diamonds up close. While this is a more advanced test, it can reveal essential details:

   • Real Diamond: Real diamonds have small imperfections or inclusions that are visible under a loupe.
   • Fake Diamond:A perfect, flawless stone is more likely to be fake or synthetic.

8. The Diamond Tester

   A diamond tester is a specialized tool that measures a stone's thermal and electrical conductivity:

   • Real Diamond: Genuine diamonds will register on both thermal and electrical conductivity tests.
   • Fake Diamond: Imitation stones like cubic zirconia will fail these tests.

Final speech

While these tests provide helpful insights into the authenticity of a diamond, the most reliable method is to consult with a certified gemologist or jewelry expert. A professional evaluation will include advanced equipment and knowledge to ensure your diamond is real.
