What You Need to Know About a Natural Black Diamond

The first thing you need to know about black diamonds is they are rare. Raw black diamonds are only found in the Central African Republic and Brazil. Black diamond has three categories:

  1. Natural or Raw Black Diamonds: This type is naturally occurring black diamonds or carbonado diamonds that possess more clusters of graphite as compared to white diamonds. That is why it possesses its black color.
  2. Treated Black Diamonds: Cheaper industry-grade white diamonds, when subjected to heat and irradiation turns into a treated black diamond. 
  3. Man-made: these are also called lab-grown diamonds that are being obtained and synthesized in the lab. There are ongoing debates about these lab-made diamonds can be classified as diamonds in the first place. 

Whether a black diamond is treated or natural, what defines a diamond is its crystalline atomic structure, especially the amorphous carbon, and chemical composition.

How to Identify a Black Diamond

The first thing you’ll notice when you first glance at a black diamond is its inclusions or small imperfections in its structure. Typically, jewelry experts would advise you to identify a black diamond using a magnifying glass. 

Here’s a fact about black diamonds: no matter how shiny or sparkly a black diamond looks from afar, it usually comes scratches and a few nicks on its surface. That’s even if it is categorized as an AAA quality black diamond, it never has a perfectly smooth surface. An AAA quality black diamond is considered to be ‘nearly perfect. 

Natural Color: Black Diamonds

The actual body color of a black diamond ranges from a nearly colorless brown, dark brown, dark green body color, olive green to black. Additionally, a black diamond is completely opaque, has a high luster which contributes to its almost metallic appearance. 

Since black diamonds have heavy inclusions, usually, cutting and polishing them may be difficult. If jewelers do, they do it with great care. 

When it comes to the color of black diamonds, you should remember that they must be uniform all throughout. If you notice dark shades of brown and a combination of black then that’s probably a fake black diamond.

How to Test if Natural Black Diamonds Are Real

So here’s a dreaded question, how can you differ a real and fake black diamond? How do you know if black diamonds are real? The goal is to determine if it’s a real diamond, like what would you do on a colorless diamond. 

There are several tests you can do at home to tell if a black diamond is real or not, here are the following: 

Waterdrop Test

A black or white diamond has a high density, and a waterdrop test can help you determine if the black diamond is real or not. You can do this test at home, if it’s raw and uncut, black diamond on a piece of jewelry is not counted. Simply take an almost filled glass of water and drop the diamond in it. If the diamond sinks to the bottom, it’s real. If the diamond floats, then it’s fake. 

Dot Test

Natural diamonds have refractive power. Refractive power is the ability of a substance to make a ray of light change direction when it enters it. When introducing light to real diamonds, the light bounces off multiple times and the light never travels on a straight line. 

This is another test you can do to determine real diamonds — the Dot Test. What should you do? Take a blank paper and draw a dot on it. Then place the flat side of the black diamond on the dot. Try looking at the pointed end of the diamond, if you see the dot, that is a fake diamond. 

Fog Test

Another test you can do to determine if black or colored diamonds are real is the Fog Test. During the Fog test, hold the diamond and breathe out a wisp of air directly to the stone. The moisture and heat of your breath will cause the diamond to fog since real diamonds are excellent conductors of heat. 

If the fog instantly disappears then the diamond is real. On the contrary, if the fog takes time to disappear, then the diamond is fake. 

The Heat test

Diamonds are extremely tough and can resist extremely high heat. Another test to determine if a black diamond is real is through the Heat Test. To do this, use a lighter to heat the black diamond for a few seconds, then drop the hot diamond immediately on a glass of water. 

If it shatters, then it is a fake diamond. If the diamond retains its form, then it is real. Fake diamonds when heated and dropped into the water shatters due to contraction of matter and sudden expansion. 

The Sparkle Test

You can tell if a black diamond is real when it reflects well under the white light. Similar to a Dot Test, hold the black diamond under a light source. If the light bounces off you can see colored beams, then the diamond is real. If it has a dull reflection when introduced to a light source, then it’s most likely fake.

After Doing the Tests Above, Here’s What You Should Do

Once you have tested the black diamond with the tests stated above, here’s one final tip to truly tell if a black diamond is real: check it’s cut. Usually, black diamonds are difficult to cut. When you check the black diamonds, check for smooth edges and if it’s cut in a precise manner.

Chances are if it has smooth edges or was cut precisely, it’s not authentic. Unless of course, if it comes with a high price tag. However, if the price is too good to be true then you should question its authenticity.
