How to Tell if a Diamond Is Real vs. Fake – Don't Be Fooled!

Buying a diamond is a significant investment, and knowing whether you're purchasing a real or fake diamond is crucial. At Exotic Diamonds  we pride ourselves on offering the highest quality diamonds and gold jewelry, with certified gemologists ready to help you make an informed decision. In this blog, we will explore different ways to determine if a diamond is real or fake and why choosing a reputable jeweler like Exotic Diamonds is essential.

1. Check for a Diamond Certificate

The first step in verifying the authenticity of a diamond is to ask for a diamond certificate. This certificate, also known as a grading report, is provided by trusted gemological laboratories like the Gemological Institute of America (GIA) or the American Gem Society (AGS). A certificate will give you detailed information about the diamond’s cut, clarity, color, and carat weight. At Exotic Diamonds, we ensure that all our diamonds come with proper certification, so you can trust the quality and authenticity of your purchase.

2. Visual Inspection of a Mounted Diamond

If a diamond is mounted in a ring or other jewelry, visual inspection becomes a bit more complex. Look for metal markings such as "14K" or "18K" for gold, or "PT" for platinum, as real diamonds are usually set in high-quality metals. Low-quality metals may indicate a fake diamond. At Exotic Diamonds in San Antonio, our jewelry is crafted with top-notch materials, ensuring the authenticity and value of every piece.

3. Can You See Through a Diamond?

A common myth is that you can check a diamond’s authenticity by looking through it. A real diamond does not allow light to pass through clearly. When held under sunlight or placed on a piece of paper, a real diamond will scatter light, making it difficult to see through. If the stone appears too clear, it may be a fake or treated diamond. When you shop at Exotic Diamonds, you’ll find only genuine diamonds that refract light beautifully.

4. Diamond Reflection Test

One reliable test to identify a real diamond is the reflection test. Place the diamond on a newspaper or white surface and observe its reflection. A real diamond produces rainbow-colored flashes, also known as "fire," when light enters and refracts through its facets. This is one of the most distinctive features of a genuine diamond. At Exotic Diamonds, we can demonstrate this test in-store to show you the brilliance of our diamonds.

5. Examine the Diamond's Sparkle

Diamonds are known for their unique sparkle. Under bright light, a real diamond should exhibit intense sparkle with sharp facets and excellent color distribution. If the stone appears dull or lacks that signature sparkle, it may not be real. At Exotic Diamonds, we hand-select our diamonds to ensure they meet the highest standards of brilliance and quality.

6. Home Tests for Identifying Real Diamonds

While professional tests are the most reliable, you can try a few simple at-home tests to determine if your diamond is real:

  • Fog Test: Breathe on the diamond to create a fog. A real diamond disperses heat quickly, so the fog should disappear almost instantly. If it lingers, the stone could be fake.

  • Heat Resistance: Real diamonds are highly heat-resistant. While we don't recommend trying this at home, heating a diamond and immediately dropping it into cold water can test its authenticity. A real diamond will remain intact, while a fake may crack or shatter.

  • Weigh It: Diamonds have a specific gravity of 3.52, making them denser than many other materials. Using a precision scale can help you verify the weight of your diamond. Fake diamonds often weigh less than genuine ones.

7. Can Diamonds Show Up on X-rays?

Since diamonds consist of carbon atoms, they have a high density, causing them to appear on X-rays as dark, opaque objects. While this method isn’t commonly used for everyday gemstone testing, it's another indicator of a real diamond's properties.

8. Check the Type of Setting

Another clue to a diamond’s authenticity is the quality of its setting. Real diamonds are typically set in high-quality metals such as gold, platinum, or sterling silver. Low-quality settings often accompany fake diamonds. At Exotic Diamonds, we use only the finest materials in our jewelry, ensuring both the stone and the setting are of the highest quality.

9. The Mirror Test

The mirror test is a simple way to check your diamond’s authenticity. Place the diamond face-down on a flat surface and observe its reflection in a mirror. If the reflection appears blurry or hazy, or if you cannot see the colorful reflection typical of a diamond, the stone may be an imitation.

10. Sand It Down (Not Recommended)

A real diamond is one of the hardest substances on Earth, making it resistant to scratches. While sanding a diamond is not recommended, lightly scratching the surface of a suspected fake diamond with sandpaper may help reveal its true nature. A real diamond will remain unscathed, while a fake stone may show signs of damage.
