Black Diamonds

What Makes a Diamond Black?

Natural fancy black diamonds get their color from dense concentrations of graphite, magnetite, hematite, or iron-bearing materials during formation. 

These inclusions block light, making the stone appear opaque. In large quantities, inclusions can make the diamond appear entirely opaque, while in smaller quantities, the black may not be uniform throughout. 

Unlike other fancy colored diamonds, only one color intensity exists (‘Fancy Black’). 

Natural vs. Treated Black Diamonds:

Fancy black diamonds can also be lab-produced by using irradiation or heating. Though this often results in a more dark green-to-black appearance than pure black. 

Natural fancy black diamonds, however, are found with their black color intact and receive a GIA certification as of natural origin. This makes them rarer and usually more expensive per carat, while treated black diamonds are more widely available and therefore often cheaper. 

Shapes & Cuts for Black Diamonds:

Round brilliant diamonds are considered the classic in diamond black engagement rings. With 57 or 78 facets, it mimics the luster and surface reflections of a diamond for a lively, polished look, though it does not display the sparkle of white diamonds. 

Pear and marquise cuts are also highly sought after, with their dramatic, elongated silhouettes providing a sleek and elegant alternative. 

Alternatively, you can consider the classic Emerald and Cushion cuts, which really showcase the depth and opaque surface beauty associated with black diamond proposal rings.

Why Choose a Black Diamond?

Black diamonds are ideal for anyone after something dramatically different from traditional diamonds. Their striking dark personality suits anyone with a leaning towards alternative or elegant fashion, and they are also suitable for men’s engagement rings. 

Whether in solitaire settings or in any custom shape, they are very versatile and serve as striking contrast stones when paired with colorless diamonds. We also recommend a dramatic contrast pairing with white gold or platinum, or a warmer, more sophisticated pairing with rose gold or yellow gold.

In terms of symbolism, black diamond rings are widely considered to represent strength, power, passion, and an eternal commitment with an edge. 

You can also rest assured that their durability is as strong as that of any other diamond, with a hardness of 10 on the Mohs scale. 

Finally, black diamond rings are often suited to smaller budgets than other fancy-colored diamonds like blue, pink, or red, while remaining genuinely very rare. 

FAQs on Black Diamond Rings

Are black diamonds real diamonds?

Yes! Natural black diamonds form in the earth over billions of years. 

What is the difference between natural and treated black diamonds?

Natural black diamonds form after billions of years, gaining their black color from inclusions of graphite and other materials. However, there are also ‘treated’ black diamonds. These diamonds began as real diamonds, too, but were made to look darker via heating or irradiation. 

How are black diamonds graded?

There is only one grade of coloration for black diamonds: fancy black. 

Unlike other diamonds, the 4Cs become less important, with greater focus on whether they are natural, treated, or lab-grown. 

The GIA provides a certification for natural fancy black diamonds. 

Do black diamonds sparkle?

Yes, but in a different way than white or colorless diamonds. Instead, you’ll see a glint or sheen, rather than a sparkle. This is caused by the reflective surface, rather than the light play within the stone.

Are black diamonds good for engagement rings?

Yes! Black diamond engagement rings are a great idea for a person who perhaps prefers the darker side of fashion.
