How to Determine if a Diamond Is Genuine?

Diamonds are not only charming gemstones but also a profound investment. Jewelry with diamonds can become a spectacular accessory that complements the image and confirms the owner's high social status.


When purchasing jewelry, it is vital to ensure it is 100% authentic. How to do this, and what characteristics should you pay attention to? Let's discover right now!


Key Characteristics of Real Diamonds

The best confirmation of a diamond’s quality is a special certificate that accompanies the stone and is provided to the buyer along with the jewelry. Specialized expert organizations and labs issue it.


This document contains information about the main characteristics of the stone that influence the diamond ring price in UAE. We will consider the key ones further. 


Brilliance and Reflectivity

Luster is a unique feature of a diamond, making it an iconic and recognizable mineral. This characteristic is also sometimes called “fire.”


Why do diamonds sparkle? This is due to numerous facets — flat cut surfaces located on the surface of the mineral. They are small mirrors that can reflect the light that hits them.


Does real diamond reflect rainbow? Yes! Small facets reflect predominantly white light, while larger facets, similar to a prism, convert the beam into different colors.


Color and Transparency

A special scale has been developed to determine the color of a diamond. It includes various possible shades — from clear (D) to darker options, including brown (Z). The most transparent stones (D-F), which transmit more light and create intense shine, are considered more valuable.


Remember charismatic colored or fancy diamonds. These gemstones have non-standard colors (blue, pink, yellow) and are valued differently.


If we talk about a diamond's transparency, it implies the absence of internal and surface defects — inclusions and stains. Stones are considered flawless if these flaws cannot be detected using professional equipment with 10x magnification.


Weight and Density

The weight unit for a diamond is a carat. Experts classify gems into small, medium, and large based on this parameter. As the weight of the mineral increases, its cost rises.


Why are we interested in diamond density? Many people believe that a transparent diamond is not visible in water. However, this statement is completely false. It turns out that the density of diamonds significantly exceeds that of water. Thus, the stone cannot “dissolve” in water, and these indicators are the best confirmation.


Home Methods for Testing Diamonds

How to test a raw diamond at home? We bring to your attention the simplest ways to help determine the characteristics of a stone.


Water Test

Take a glass of water, place a diamond in it, and evaluate what happens with the mineral next.


As we said above, the legendary gemstone's density is much higher than water's. That is why the stone is visible in it and sinks quickly. With fakes, everything is the opposite. Imitation stones can remain on the surface for a long time without sinking deep into the testing container.


Fog Test

Another easy way to determine a diamond's authenticity is to breathe on it.


True mineral dissipates heat quickly. Thanks to this feature, no condensation remains on its surface. As for fakes, they will fog up and remain foggy for a few moments.


Using Ultraviolet Light

Do you have a UV lamp on hand? Try to check how a diamond reacts to ultraviolet light!


Shine a light on the stone and evaluate the result. When exposed to UV rays, most real diamonds show blue fluorescence.


It should be emphasized, however, that real minerals may not have this ability. Conversely, some fakes may fluoresce. Therefore, the result of this test requires further confirmation.


Heat Conductivity: Simple Heat Test

All you need to do is squeeze the diamond in your palm. Hold it in your hand for a while, and then evaluate how your sensations have changed.


This mineral heats up extremely slowly. If the diamond is genuine, it will remain cool even after a few minutes of this experiment.


Professional Methods for Testing Diamonds

Professional diamond testing is carried out on a different level. It includes more complex methods that guarantee higher reliability of the obtained values.


Professional testing of minerals helps determine a real diamond and performs several additional functions:


  • Ensuring proper pricing. Accurate identification and classification of minerals guarantee a safe and sound investment.

  • Certification to determine the characteristics of a diamond (clarity, cut, carat weight) to confirm the mineral's properties and increase its market value.

  • Providing transparency to identify treatments and additional improvements to the stone to increase its price.

  • Compliance with industry standards to increase consumer confidence in the diamond market and support its reputation.


Thus, professional diamond testing is a must today. Let's find out how it can be done.


Using a Loupe for Detailed Examination

How to know a good diamond? One of the most common ways is to use a magnifying glass that provides 10x magnification.


  • Using this tool, specialists determine the presence of various inclusions and defects. Genuine minerals tend to have natural imperfections, but synthetic stones do not.
  • Also, during the inspection, the edges deserve special attention: for natural diamonds, they should be sharp and clear, while for fakes, more rounded or polished edges are typical.
  • Finally, special markings can be detected with the help of a professional magnifying glass. Diamonds may have laser markings on their surfaces that contain certification details.

Checking with Thermal Conductivity 

You can squeeze the stone in your hand at home to check its thermal conductivity. However, professionals use a specialized diamond tester for this purpose.


This device specifically measures thermal conductivity, helping determine a diamond's authenticity. A stone that dissipates heat quickly will be considered natural.


At the same time, remember that even a professional product can give false positive results. In particular, they can be observed when studying moissanite, a diamond simulator. Its distinctive feature is high thermal conductivity, which can mislead even experienced specialists.


Electrical Conductivity: How to Distinguish a Diamond from Moissanite

How to distinguish a natural diamond from moissanite? One of the most reliable methods is testing with a conductivity tester.


Diamonds are poor conductors of electricity, while moissanites are vice versa. As a result, the tester demonstrates low conductivity for natural minerals and high for simulant stones.


The difference between a diamond and moissanite can be seen without further testing during a classic visual inspection. A simulant stone can exhibit the effect of doubling its faces. However, it can only be detected from a certain angle, requiring experience and specific responsibility from the specialist.


As you can see, there are many ways to determine the authenticity of diamonds, both at home and in a professional laboratory. Thanks to them, you can be confident in the authenticity of the precious stone you are purchasing and the safety of your investment.
