בדיקה אמיתית או מזויפת - בדיקה עצמית בבית

There are several simple tests you can try at home to check if a diamond is real or fake:

Water Test

• Fill a glass with water and gently drop the diamond into it.
• A real diamond will sink to the bottom due to its high density, while a fake diamond will float or remain suspended in the water.

  Fog Test

• Hold the diamond or ring between two fingers and breathe on it with a puff of air.
• A real diamond will disperse the heat quickly, and the fog will dissipate almost instantly.
• If the fog takes a few seconds to clear, it might be a fake.

  Dot Test

• Draw a small dot on a piece of paper.
• Place the diamond flat side down over the dot and look through the top of the diamond.
• If you can see the dot or a reflection inside the diamond, it's likely a fake.
• A real diamond will not show the dot due to its refractive properties.

  Heat Test

• Use a lighter to heat the diamond for a few seconds.
• A real diamond will not be affected by the heat, while a fake diamond may crack or shatter.

  UV Light Test

• Expose the diamond to UV light.
• Some diamonds will fluoresce under UV light, while others won't3.
• Note: Not all real diamonds fluoresce, so this test is not definitive.

  Scratch Test

• Try to scratch a piece of glass with the diamond.
• A real diamond will scratch glass, while a fake one will not.

  Check the Setting and Mount

• Look at the metal setting of the diamond.
• Real diamonds are usually set in high-quality metals like gold, platinum, or silver.
• If the setting is made of a lower-quality metal, it might indicate a fake diamond.
• SANDPAPER TEST
• Riskier test* Acquire sandpaper and sandpaper the stone; make absolutely certain that it is regular sandpaper and not one that is covered with diamond powder.
• Unscratched? It’s real!
• Scratched? It’s fake…   
• SCRATCH TEST
• Scratch the stone against glass. 
• Glass is scraped? It’s real!
• Glass is unscratched? It’s fake…   
• LOUPE TEST
• Acquire a loupe (magnifying glass) & look for imperfections. Most diamonds have them but fakes look perfect.  Also counterfeit diamonds typically have somewhat rounded edges.
• Some imperfections? It’s real!
• Perfection? It’s fake…
• SPARKLE TEST
• Hold the stone in the light to observe its sparkle. Diamonds have high refractive index so they sparkle more than other materials.
• Outdoors: it reflects rainbow colors? It’s real!
• Indoors: it reflects rainbow colors? It’s fake…

  Professional Testing:

• If you're still unsure, consider taking the diamond to a professional jeweler for a definitive test.

Remember, these tests can give you a good indication, but they are not foolproof. For a conclusive result, it's best to consult a professional jeweler or gemologist.
