Have you ever questioned the authenticity of your diamond jewelry or been suspicious that a loose natural diamonds you purchased wasn’t real? You can be confident that the stone is authentic if it has an AGS or GIA certificate. You have every right to question, though, if the diamond was given to you or inherited and you do not have the certificate.

Are you unsure of your diamond jewelry? Do you ever think if they are authentic or fake? Have you been suspicious that a loose diamond you purchased wasn’t real? You can be confident that the stone is authentic if the dealer has certifications.

You have every right to question, though, if the diamond was given to you or inherited and you do not have the certificate. We are going to discuss how you can check the authenticity of diamonds. For this, we can run some tests, which include a whole list, so let’s discuss them in detail in the following paragraphs.

1. Scratch Test

The “scratch test” was once thought to be the simplest method for evaluating a diamond. Just scrape the loose stone against a mirror to test it. The theory goes that the stone is most likely a diamond if it is hard enough to scratch the mirror. However, this test turns out to be unreliable when it comes to the Mohs scale. A scientific way to determine the hardness of minerals is with the Mohs scale.

The hardest mineral, diamonds, they are on 10th rating, while you can rate glass 5.5. Thus, natural diamonds will leave scratches on a mirror. However, so will moissanite (9.25), cubic zirconia (8), and quartz (7).

Engagement rings consisting of moissanite and cubic zirconia are nearly as durable as those consisting of diamonds. Applying merely the scratch test will make the majority of well-made synthetic diamonds appear real. These are some more tests with more trustworthy outcomes.

2. Magnification Test

What you require:

How it works: Use a microscope to examine your dubious stone first. Next, examine the real diamond and contrast the variations. Inclusions and blemishes are imperfections, either internal or exterior that are present in natural diamonds. Should the other stone be moissanite or cubic zirconia, it will likely be flawless both inside and out.

This is so because you can make moissanite and cubic zirconia in laboratories, but natural diamonds are naturally occurring rocks that were formed in the ground. They lack the distinctive characteristics that distinguish a genuine diamond since they don’t come in contact with the same environmental stresses as diamonds during their formation.

3. Fog Test

Fog test it holds onto heat what you require:

Dubious Diamond Stone Fog Test

How it works: For the fog test, place yourself somewhere reasonably cool, then blow hot air onto the stone. Just be careful; if you do this in the middle of Central Park, you might receive some strange looks.

You’re attempting to envelop the stone in a warm, humid atmosphere. Breath does not cause a fog to form on the surface of a real diamond. This is because they are not good heat retainers. However, a moissanite piece will quickly fog up, just like your phone screen, eyeglasses, or mirror.

4. The Test with Black Light (Doesn’t Glow)

What you require:

How it works: The black light test works when you place the stone under the UV light and observe any changes in color. A bluish hue indicates that the stone is probably a genuine diamond. The results of this test are not conclusive due to the nature of fluorescence in genuine diamonds. If it were real, there wouldn’t be a blue glow because some natural diamonds don’t have any fluorescence at all.

You can repeat these tests at home if the stone doesn’t glow blue or glows a different color when you make contact with the UV light. You should take it to a competent jeweler to get the most conclusive response.

5. Completely Visible Through the Test of Newspapers

What you require:

The newspaper test method is as follows: Set the stone on top of the newspaper and check to see whether you can see the words through it. If a genuine diamond is of good quality, it will refract light so strongly that it is impossible to see through. You can look right through cubic zirconia, on the other hand, because it is more translucent.

Warnings: If the stone is less than a half-carat in size or you place it in jewelry that may obstruct your view, this test is less accurate.

6. The Heat Is Too Much for It: Using A Candle or Lighter

What you require:

How it works: For about 30 to 45 seconds, heat the loose stone with the tweezers while holding it over a lighter or candle flame. Then, plunge it right into the freezing water. Since real loose natural diamonds consist of incredibly strong material, they won’t react to this drastic temperature change. Nevertheless, a lot of imitation diamonds, such as those composed of quartz, glass, or cubic zirconia. Also, it will crack or shatter in this test.

Caution: If your stone passes this test, congratulations! However, be ready to remove any remaining ash from the flame afterward. The easiest method is to use a toothbrush to gently scrub it clean after soaking it in warm water and toothpaste solution for at least three minutes. Additionally, remember to rinse!

7. The Test of Water(Buoyant)

What you require:

To use a water test, just toss the loose stone into the water. Dropping loose diamonds into a glass of water. It should cause them to sink to the bottom due to their high density. Because glass and quartz are less dense than natural diamonds, many of them will float or take longer to sink.

Notes: This test is not must reliable. Large pieces of moissanite and cubic zirconia, while not as dense as diamonds. They can sink fairly quickly if they are heavy enough.

8. The Test for Conductivity Electrically Resistant

What you need: For the conductivity test, you will need to leave the house. Bring your stone to a nearby jewelry maker.

How it works: Diamonds resist electricity, which is something that not many people are aware of. If the type of stone you have is unclear, diamond or moissanite, you can determine its electric conductivity by testing it loose.

How Do You Use A Diamond Tester?

If you have to identify whether a stone is a genuine diamond, diamond testers have a metal tip at the end. It gauges the unique thermal conductivity of diamonds. When you press the diamond or natural gemstone up against the sprung metal tip, it gives out indications.

For instance, an LED reading indicates whether or not the stone is a real diamond. The majority of devices are small and run on batteries.

Can SI Natural Diamonds Pass a Test for Diamond Quality?

Yes, without a doubt. The majority of included diamonds and SI natural diamonds pass a diamond tester. They function similarly in tests and have the same thermal conductivity as diamonds.

Why Does A Natural Diamonds Glow When Exposed To UV Light?

A diamond that glows in the presence of UV light is not a fake or artificial one. Certain diamonds have variable degrees of UV light reflection. Some natural diamonds, therefore, seem to glow when exposed to strong UV light. Visit our website’s education section to learn more about fluorescence.

The following image, which we captured of a package of tiny natural diamonds, demonstrates how some diamonds glow in the presence of ultraviolet light. Simultaneously, some diamonds within the same parcel exhibit negligible or no fluorescence.

Conclusion:

Try some of these at-home tests if you have a loose diamond or a piece of jewelry and you’re not sure if it’s real. Alternatively, you can take the stone to any of the UOI Gold Diamond.
