It’s important to know how to distinguish a real diamond from a fake one, especially when making a significant investment. Here are some simple ways to determine if a diamond is real:
1. Check for flaws
Real diamonds typically have imperfections known as inclusions, while fake diamonds are usually flawless. Use a jeweler’s loupe to inspect the diamond closely for any flaws.
2. Conduct a fog test
Breathe on the diamond, and if the fog dissipates quickly, it could be real. If the fog lingers for more than a few seconds, it’s likely fake.
3. Perform a transparency test
Place the diamond over a piece of newspaper or text. If you can read the text through the diamond, it’s likely fake. A real diamond refracts light, making it impossible to see through.
4. Test the diamond’s conductivity
Real diamonds are excellent conductors of heat, so touch the diamond to see if it feels cold to the touch. Fake diamonds do not conduct heat well and may feel warm.
5. Use a diamond tester
A diamond tester is a specialized tool that detects the thermal conductivity of diamonds. By using this device, you can determine if the diamond is real or fake quickly and accurately.
6. Seek professional help
If you’re still unsure about the authenticity of a diamond, take it to a reputable jeweler or gemologist for a professional assessment.

By following these methods, you can confidently determine whether a diamond is real and make an informed decision when purchasing or evaluating fine jewelry.
FAQs:
1. Can fake diamonds scratch glass?
Fake diamonds, such as cubic zirconia or moissanite, are hard enough to scratch glass. However, real diamonds can also scratch glass, so this test is not definitive.
2. Do real diamonds glow under UV light?
Some real diamonds exhibit fluorescence under UV light, emitting a blue glow. However, this is not a foolproof test, as not all diamonds fluoresce.
3. How can I tell if a diamond is synthetic?
Synthetic diamonds have the same physical and chemical properties as natural diamonds. The best way to distinguish them is through certification or expert testing.
4. Are there any visual cues to identify real diamonds?
Real diamonds often have a sparkle known as “diamond fire” that is difficult to replicate in fake stones. They also reflect light in unique ways due to their precise cut.
5. Do real diamonds have a specific weight?
Real diamonds have a standard density of 3.52 grams per cubic centimeter, so weighing a diamond can provide clues about its authenticity. However, this method alone is not conclusive.
6. Can real diamonds be magnetic?
Real diamonds are not magnetic, so using a magnet to test a diamond’s authenticity can help differentiate between real and fake stones.
7. Do real diamonds have imperfections?
Real diamonds often have internal imperfections called inclusions and external blemishes known as blemishes. These natural flaws can be seen under magnification.
8. Can real diamonds break easily?
While diamonds are the hardest known mineral and can only be scratched by another diamond, they can still chip or break if subjected to extreme force or pressure.
9. Do real diamonds have a specific hardness level?
Diamonds have a hardness level of 10 on the Mohs scale, making them the hardest natural substance. This hardness can help identify real diamonds from imitations.
10. Can real diamonds be submerged in water?
Real diamonds do not absorb water, so you can submerge them without causing damage. However, this is not a reliable test for determining a diamond’s authenticity.
11. How can I tell if a diamond is real by looking at the setting?
Real diamonds are often set in high-quality materials like gold or platinum, while fake diamonds may be set in cheaper metals like brass. Examining the setting can provide clues about a diamond’s authenticity.
12. Is a real diamond always clear and colorless?
Not all real diamonds are clear and colorless. Natural diamonds can come in various colors, including yellow, brown, pink, and blue. The presence of color does not necessarily indicate a fake diamond.
