What is the Difference Between Real and Fake Diamond?

The difference between real and fake diamonds can be identified through various methods. Here are some key ways to distinguish between the two:

1. Light Reflection: Real diamonds reflect light in shades of gray, while fake diamonds exhibit rainbow colors inside the stone.
2. Natural Imperfections: A real diamond will have some blemishes, color dots, and traces of minerals, while a fake diamond, being lab-created, will appear flawless.
3. Heat Conductivity: Diamonds retain heat, so when you breathe on a diamond, it will fog up and immediately clear up, whereas a fake diamond may take several seconds for the fog to dissipate.
4. Weight: Diamonds have a specific weight, being heavier than cubic zirconia and lighter than moissanite. Measuring the weight of the stone can help determine if it is real or fake.
5. UV Light Test: Most diamonds emit a bluish glow under UV light, while fake diamonds may not.
6. Type of Setting: Rings made with 10K, 14K, or 18K gold or marked 585, 750, 900, 950, PT, or Plat are more likely to hold real diamonds. However, this method is not foolproof.
7. Fog Test: A real diamond will immediately clear up when breathed upon, while a fake diamond may take several seconds for the fog to dissipate.

Keep in mind that no single at-home test should be regarded as conclusive. A diamond expert has the proper experience and equipment to confirm if a diamond is real or fake.

The differences between real and fake diamonds can be identified through various tests and observations. Here is a table summarizing the main differences:

Keep in mind that these tests are not foolproof, and it is always best to consult a professional gemologist for a definitive assessment of a diamond's authenticity.
