How to Tell if a Diamond is Real: Complete Guide to Identifying Authentic Jewelry

Are you looking to buy a diamond jewelry piece and wondering how to tell if they are real? In this article, we will provide you with a complete guide so you can easily identify whether a diamond is genuine or not.

Diamonds are precious stones that are coveted for their beauty and value. However, they are also a common target for counterfeits and imitations. That's why it's important to know how to recognize a real diamond before making any purchase.

At Neogold, our Colombian jewelry store specializing in exclusive pieces for men and women, we have dedicated ourselves to creating 18k gold jewelry with authentic precious stones. We use 3D technology to design unique, custom-made pieces. That's why we want to share with you some key tips so you can identify a real diamond.

Characteristics of a real diamond

There are several characteristics that differentiate a genuine diamond from a fake one. Below we will explain the most important ones:

1. Brightness and refraction of light

Real diamonds have a unique brilliance and light refraction. When light enters a diamond, it refracts and reflects in multiple directions, creating a "fire" and "sparkle" effect that is difficult to imitate.

If you hold the diamond up to the light and notice that the light scatters and creates flashes of color, it is most likely a real diamond. Synthetic or imitation diamonds, on the other hand, do not achieve this same effect.

2. Hardness and resistance

Diamonds are the hardest stone found in nature, with a hardness of 10 on the Mohs scale. This means that they are extremely resistant to scratches and impacts.

You can test the hardness of a diamond by gently rubbing it against a watch glass or mirror. If it doesn't leave any marks, it's most likely a real diamond. Diamond imitations, such as cubic zirconia, are softer and scratch more easily.

3. Inclusions and defects

Natural diamonds always have small imperfections or inclusions inside them, such as gas bubbles, crystals, or fractures. These inclusions are unique and give each diamond its own "fingerprint."

If you look at the diamond with a magnifying glass or microscope, you will be able to see these small inclusions. Synthetic diamonds or imitations, on the other hand, are often too perfect and lack these natural imperfections.

4. Specific weight

Diamonds have a higher specific gravity than most imitations. You can test this by immersing the diamond in water and observing how much it sinks. A real diamond will sink faster than an imitation.

5. Certification and documentation

Finally, it is important that the diamond is accompanied by a certificate of authenticity issued by a recognized gemological laboratory, such as the GIA (Gemological Institute of America) or the IGI (International Gemological Institute).

These certificates provide detailed information about the diamond's characteristics, such as its clarity, color, cut, and origin. Be sure to request and carefully review this document before making any purchase.

How to identify a fake diamond

In addition to the characteristics mentioned above, there are other ways to detect if a diamond is fake:

1. Magnet test

Diamonds are not magnetic, so if the diamond sticks to a magnet, it is a sign that it is a fake.

2. Magnifying glass test

Look at the diamond under a magnifying glass with at least 10x magnification. If you see that the surface has a repeating or regular pattern, it is likely a synthetic diamond.

3. Breathing test

Breathe close to the diamond and see if it fogs up. If it fogs up, it's a sign that it's not a real diamond.

4. Friction test

Gently rub the diamond against the glass of a watch or mirror. If it leaves a mark, it is likely a fake.

Remember that if you have any doubts about the authenticity of a diamond, it is best to consult with a trusted expert jeweler or gemologist before making the purchase.
