Black Lab Grown Diamonds and Carbonados: Where and How to Buy

Red, yellow, purple, colorless, and black – diamonds are available in a wide range of colors and hues. Black diamonds are rare and unique, fancied by only a few.

However, with increasing popularity, many customers and diamond enthusiasts are looking to buy black diamonds of lab grown diamond variety.

In this blog, we learn all about black diamonds, how to buy them and from where to buy black diamonds.

What are Black Diamonds?

Black diamonds or carbonados are a unique type of diamond. These diamonds consist of many small diamond crystals combined together. This is called polycrystalline. The color of these diamonds ranges from charcoal to jet black, which is what makes them stand out from colorless diamonds. They are available in both lab grown diamonds and mined.

Characteristics of Black Diamonds

• Carbonados have many impurities, have high density and are micro porous.

• They contain minor crystalline precipitates filling pores and occasionally reduced metal diamond inclusions.

• These diamonds are more porous compared to other mined and lab grown diamonds.

• The natural color of black diamonds is black or dark grey.

• They display strong luminescence.

Origin of Black Diamonds

There are many theories around the origin of black diamonds. Although, in the recent past, the industry has seen synthetic diamonds that are black, earlier, there were only mined black diamonds.

One theory suggests extraterrestrial activities, such as a meteoric impact or an asteroid collision, are responsible for the formation of black diamonds.

Another theory suggests black diamonds were formed due to radiation on the earth. Some scientists also believe that black diamonds are formed in the same way as regular diamonds, under severe pressure and temperature.

How are Black Diamonds Graded?

Whether black diamonds are mined or synthetic diamonds, they are considered fancy diamonds. They are therefore graded differently than the way colorless diamonds are graded.

As the demand for black diamonds is lower than colorless diamonds, their prices tend to be lesser than colorless diamonds. In recent years, the popularity of black diamonds has increased as they are unique and make a fashion statement.

Lab grown diamonds of black color are made through two processes — High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Black diamonds are graded for the same parameters as other diamonds – color, clarity, carat, and cut.

How to Buy Black Diamonds

• When you buy mined or lab grown diamonds, you must check the certificate of the diamond.

• The most important factor when buying a lab grown diamond that is black is its cut. The better the cut quality, the more expensive the diamond would be.

• Black diamonds come in many colors; choose the color — salt and pepper or fancy black — based on your personal preference.
