Black Diamonds – A Buyers Guide to Black Diamond Rings

1 Carat pair of Black Diamonds

Are black-coloured diamonds real?

Black diamonds are real. When most people think about diamonds, they imagine white diamonds. In fact, they rarely think of black diamond rings in the same way as traditional engagement ring styles.

Very few buyers choose a black diamond ring. In fact, it makes a fresh alternative to traditional white diamond engagement ring styles. Moreover, they represent the least expensive type of diamond available.

Famous Black Diamonds

Famous examples exist throughout history. For example, the 67.50-carat ‘Black Orlov’ (also called the Eye of Brahman). Legend has it, the stone was stolen from an idol in India early in the 1800s.

Contrary to popular belief, this unusual form of diamond lacks the same see-through appearance as a white diamond. They are completely opaque. Furthermore, most have a metallic appearance similar to Haematite.

The rise in demand for Black jewellery design

Historically, little need existed until fairly recently. Late in the 20th Century, jewellery designs began working with fancy black diamonds. Many jewellers varied the black and white pattern with striking effects.

Black and white diamonds create contrast across a piece of jewellery with a dramatic effect.

In the movies, the rise of the black engagement ring appeared when Mr Big gave Carrie Fisher a five-carat diamond engagement ring in the movie Sex in the City 2.

Further mention came as Carmen Electra and tattoo artist Kat Von D paraded their engagement ring just a couple of years later.

Besides engagement rings, our collection includes other types of black jewellery. For example, black wedding rings.

Black diamond engagement rings?

There are a few reasons why I think such diamonds appeal to some buyers. Firstly, they offer a unique variation on the popular white diamond engagement ring.

Secondly, they are less expensive than white diamonds, making them an attractive alternative to traditional diamond ring. We create most designs with round stones. Alternative fancy diamond shapes exist but beware of weak points and corners on some diamond shapes.

Natural vs Treated.

Natural black diamonds are Carbonado, a raw form of polycrystalline diamond made up of diamond, graphite, and amorphous carbon. All natural diamonds formed between 1 to 3.5 billion years ago in the Earth’s Mantle 250 km below the surface.

Some sources suggest the existence of this type of diamond in outer space. Perhaps, due to a collision with Earth, billions of years ago.

Natural colored diamonds are more porous than white colorless diamonds. As a result, it can be more difficult for diamond cutters to achieve good polish. Think of a natural black coloured diamond as diamonds with an incredible amount of inclusions stopping light from passing into the diamond. Tiny mineral inclusions including graphite, pyrite or Haematite spread throughout the stone give the material its black colour.

Treated Black Diamonds

Treated diamonds start as natural low clarity diamonds. White diamonds of very low clarity go through a treatment process to change the stone colour. Technicians color black diamonds using specific treatments to change the way light reflects from the stone.

Many treated examples start as grey, heavily included or fractured diamonds and get their color through a process of high-temperature/low-pressure treatments. This process darkens the fractures, making them black.

The treatment of some stones can also produce a green so dark the stone appears to the naked eye as black. Not every diamond dealer stocks coloured diamonds. On the contrary, most diamond dealers work mainly with white diamonds.

Caring for your diamond

Diamonds are very hard. Generally speaking, they have the same natural hardness as white diamonds. However, owing to the stones having so many marks, they’re more prone to breakage.

Also, they smear easily during daily wear. For example, grease and oils show visibly on a black gemstone. For this reason, it is crucial to keep your ring clean. Our Dry Wipes and DazzleStik work very well for this purpose.

How to wear jewellery

Black diamond jewelry designs often feature white diamonds for contrast. In the same way, Platinum and White Gold provide the necessary contrast with any black gemstone. However, many designs add warmth and colour with Rose Gold and Yellow Gold settings.

For example, Dress rings set small pavé diamonds in both colours look amazing. As shown below, the difference makes a statement. Many jewellers achieve contrast by setting both colours next to each other.

Black diamond eternity rings

Set into an eternity ring, we achieve incredible combinations. At the same time, styles deviate from more traditional eternity ring designs.

Again, try mixing white with black. Striped black and white eternity ring designs stand out on the finger. Furthermore, fewer jewellers feature such designs. As a result, they create the opportunity to be a little different.

Black diamond pendants

Besides single stone settings, many alternative pendant styles exist. For example, the necklace below shows a circular design. The whiteness of the Rhodium and white diamonds add a beautiful level of contrast to the pendant.

Diamond earrings

In the same fashion, black diamond earrings look amazing. Black stud earrings require a matching pair of black stones. But, pairing diamonds can be tricky. 

By comparison, cluster earrings feature tiny diamonds. As a result, they are easier to match cut into smaller sizes. Decide whether you want classic stud earring styles, or contrasting black and white diamond earrings.

Black diamond hoop earrings look incredible. Here, we see black pavé-set diamonds appear on the outside. Inner diamonds provide a diamond paved appearance. Each section includes Black Rhodium for an even look.

In reality, both black and white diamond earrings work with most outfits—moreover, both suit daytime or evening wear. Unlike rings, earrings have little wear. As a result, there is less risk of damaging black diamonds.

Black Diamond Necklaces

Our example below made a rare appearance in our shop. Originating in India, the 18ct Yellow Gold necklace features and arrangement of drilled and strung diamonds.

For anyone interested in alternative choices to black-coloured diamonds, we work with two further types of diamonds. Salt and Pepper diamonds and Galaxy diamonds make a feature of their lack of clarity.
