Features to Consider When Buying Black Diamonds (Buyer’s Guide)

Here are some of the essential diamond information you need to know before you make an informed purchase:

Color

Natural black diamonds are originally colorless diamonds or a clump of opaque stones with several quantities or clouds of mineral inclusions such as graphite. Unlike white diamonds found in a single large crystal, black diamonds consist of multiple smaller crystals. You will see the black color caused by inclusions and the mineral structure, which absorbs light instead of reflecting it. 

Black diamonds are often low-quality, made from colorless diamonds in a rough state. The stones go through a heat treatment process to achieve the desired black color. 

Cut

The high graphite inclusions found in natural black diamonds make them difficult to cut and polish without fracturing them. It often results in a time-consuming and highly intensive process. As much as possible, always pick a round brilliant-cut black diamond.

Clarity & Luster

Since black diamonds have a naturally occurring state of being heavily included and opaque, the GIA does not qualify them for the clarity scale. Given its black color, a black diamond does not refract light, including its white counterparts. However, a black diamond should sparkle with high luster with a uniform color and almost metallic appearance.

Carat

Since black diamonds are denser than fancy-colored diamonds, these stones may still look smaller despite the same number of carats. One example, a one-carat natural black diamond may look fairly smaller than a one-carat white diamond.


Conclusion

Black diamonds are truly an intriguing precious stone. Although they are largely undesired in the past, these stones made newfound popularity, thanks to clever marketing tactics and high-profile celebrities and personalities.

Although black diamonds don’t have the luster and color offered by fancy-colored diamonds, they still hold their precious value behind a veil of mystery. Whether you want something unique for your engagement ring, jewelry collection, or heirloom, black diamonds will surely stand out. 

This diamond buying guide has provided the best finds for black diamonds from James Allen and Blue Nile. It includes the 3.18-Carat Fancy Black Round Diamond by James Allen, the top pick for the best black diamond. 

This black bedazzled gem offers unbelievable sparkle and brightness. It has a versatile circular shape, allowing you to match it with any jewelry setting. It is also a stunning center stone for a unique, non-conventional engagement ring. Not only that, this stone offers an impressive character and beauty that you can cherish for many years.

It is highly recommended to purchase stones in jewelers that offer an accompanying certificate from a reputable gemological laboratory, such as the GIA. This way, you can be sure that you are getting a real deal and the best value for your money.


FAQs (Frequently Asked Questions)

What is the difference between natural and treated black diamonds?

Black diamonds come in two types: natural fancy black diamonds and treated or enhanced black diamonds. Natural black diamonds obtain their hue from graphite inclusions and are rare, found only in Brazil and Central Africa. 

Meanwhile, treated black diamonds are originally colorless diamonds. They are transformed into black through heat or radiation treatments. Colorless diamonds with several inclusions are often picked to go through this process. Its unattractive inclusions will almost turn invisible once the diamond’s surface has turned black and opaque. 

Salt and paper diamonds are another black diamond variety. They have several inclusions but are translucent. They also have a black and white speckled appearance.  

How should I wear black diamonds?

Black diamonds make a unique engagement ring or fine jewelry. You can pair a black diamond with rubies or colorless diamonds in a platinum band for those who want a modern jewelry piece. Although diamonds are very hard and won’t scratch, they are still susceptible to damage due to their brittleness. Smaller black diamonds have a lesser possibility to fracture than bigger ones.

If you want a black diamond but don’t want to worry about breaking or cracking, you can incorporate them in a wedding band or pair them with other center stones. Citrine, emeralds, rubies, and colorless diamonds look incredibly brilliant when surrounded by black diamonds.

Are black diamonds make a good investment?

Although they are not considered a stone for diamond investors, natural black diamonds are experiencing a surge in popularity. It means that a black diamond’s price has now increased alongside white diamonds, which used to be comparatively low. 

Those planning to invest in black diamonds should find a stone with a considerable size or a distinctive feature that adds to its value. However, investors are advised to be very careful as the increasing demand for these stones has led to a growing market for artificially-treated black diamonds. They come at cheaper prices with a significantly lower quality than authentic black diamonds. You can keep it from happening if you consult diamond experts to help you find the right deal.
