Diamonds are one of the most valuable gemstones in the world, and it is not uncommon for people to aspire to own one. However, not all diamonds are authentic, and it is important to know how to tell whether a diamond is real or fake. With advancements in technology, it has become easier for fraudsters to create fake diamonds that look very similar to the real ones, so it is worth knowing how to distinguish between a real diamond and a fake one. In this article, we will understand some of the most effective ways to determine whether a diamond is real.
1. The Fog Test
One of the simplest tests to determine the authenticity of a loose diamond is the fog test. This test works because a real diamond does not hold heat, so the fog created by breathing on the diamond will disappear quickly. To perform this test, breathe on the diamond and observe how the fog disappears. If the fog disappears within a second or two the diamond is likely to be real and if the fog lingers, the diamond may be fake.
2. The Loupe Test
A loupe is a small magnifying glass commonly used in the jewelry industry. This tool can be an excellent way to check the authenticity of a loose diamond because it allows you to examine the diamond's internal and external features. To perform this test, examine the diamond through the loupe, looking for inclusions or blemishes. Real diamonds have inclusions, in the form of tiny imperfections which are naturally present and unique to each diamond. Fake diamonds, on the other hand, are usually flawless, and therefore lack inclusions.
3. The Water Test
Another easy test to determine whether a diamond is fake or real is the water test. To perform this test, you can place the diamond in a glass of water. If the diamond is real, it will sink to the bottom of the glass. Fake diamonds usually float or remain suspended in the water. This is because a real diamond is denser than water, while fake diamonds are typically made of lighter materials and have a lower density.
4. The Ultraviolet Light Test
This test requires a UV light source, such as a black light. To perform this test, hold the diamond under the UV light and observe the diamond's reaction. Real diamonds emit a blue fluorescence under UV light, while fake diamonds will not emit any fluorescence. If the diamond you are testing emits a yellow or green fluorescence, it is most likely to be fake.
5. The Heat Test
The heat test is another way to test the authenticity of diamonds. To perform this test, hold the diamond close to a hot surface, such as a stove or a spirit lamp. If the loose diamond is real, it will not change color or show any signs of damage. If the diamond is fake, it may change color or become damaged due to heat. This is because real diamonds are extremely durable and can withstand high temperatures, while fake diamonds are typically made of less heat-resistant materials.
6. The Refraction Test
The refraction test involves examining the way light passes through the loose diamond. You can perform this test by holding the diamond in front of a light source and observing how the light gets refracted when it passes through the diamond. Real diamonds have a high refractive index. So, when light enters a real diamond, it bends at a high angle. This results in the diamond appearing to be very sparkly. Fake diamonds, on the other hand, have a lower refractive index, which means that light does not bend as much, resulting in a duller appearance.
Even after all these tests, if you are unsure whether a diamond is real or not, the best option is to have it appraised by a professional. Reputed gemstone sellers have a team of professionals who examine each and every gemstone minutely. You also get authenticating certificates with diamonds; this reduces your effort and saves a lot of time. So pick a loose diamond or diamond jewelry from a renowned online jewelry seller and get it delivered to your doorstep effortlessly.
