Are black-coloured diamonds real?<\/span><\/h2>\n\n\n\n

Black diamonds are real.\u00a0<\/span>When most people think about diamonds, they imagine white<\/span><\/a> diamonds. They rarely think of black<\/span> diamond rings in the same way as traditional engagement ring styles. <\/p>\n\n\n\n

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. <\/p>\n\n\n\n

Famous Black Diamonds<\/span><\/h2>\n\n\n\n

Famous examples exist throughout history. For example, the 67.50-carat ‘Black Orlov’ (also called the\u00a0<\/span>Eye of Brahman<\/span><\/em>). L<\/span>egend has it that the stone was stolen from an idol in India in the early 1800s.<\/span><\/p>\n\n\n\n

Contrary to popular belief, this unusual form of diamond does not have the same transparent<\/span> appearance as a white diamond. They are completely opaque. Furthermore, most have a metallic appearance similar to hematite.<\/span><\/p>\n\n\n\n

The rise in demand for Black jewellery design<\/span><\/h2>\n\n\n\n

Historically, there was little need until fairly recently. Late in the 20th Century,\u00a0<\/span>jewellery designs began working with fancy black diamonds<\/span><\/a>. Many jewellers varied the b<\/span>lack and white pattern with striking effects. <\/span><\/p>\n\n\n\n

Black and white diamonds create contrast across a piece of jewellery with a dramatic effect. <\/span><\/p>\n\n\n\n

In the movies, the rise of the black engagement ring a<\/span>ppeared when Mr Big gave Carrie Fisher a five-carat diamond engagement ring in the movie\u00a0<\/span>Sex and the City 2<\/span><\/em>. <\/span><\/p>\n\n\n\n

Further m<\/span>ention came as Carmen Electra and tattoo artist Kat Von D paraded their engagement ring just a couple of years later.<\/span><\/p>\n\n\n\n

Besides engagement rings, our collection includes other types of black jewellery. For example, black wedding rings<\/a>.<\/p>\n\n\n\n

Black diamond engagement rings?<\/span><\/h2>\n\n\n\n

There are a few reasons why I think such diamond<\/span>s appeal to some buyers. Firstly, they offer a unique variation on the <\/span>popular white diamond engagement ring<\/span><\/a>. <\/span><\/p>\n\n\n\n

Secondly, they are less expensive than white diamonds, making them an attractive alternative to a <\/span>traditional diamond ring. We create most designs with round stones. Alternative fancy diamond shapes exist, but be aware of weak points and corners in some diamond shapes.<\/span><\/p>\n\n\n\n

Natural vs Treated.<\/span><\/h2>\n\n\n\n

Natural black diamonds are Carbonado, a raw form of <\/span>polycrystalline<\/span><\/a> diamond made up of diamond, <\/span>graphite<\/span><\/a>, 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.<\/span><\/p>\n\n\n\n

Some sources suggest the\u00a0<\/span>existence of this type of diamond in outer space<\/span><\/a>. Perhaps, due to a collision with Earth billions of years ago.<\/span><\/p>\n\n\n\n

Natural-coloured diamonds are more porous than white, colourless diamonds. As a result, it can be more difficult for diamond cutters to achieve good polish. <\/span>Think of a natural black coloured diamond as a diamond with an\u00a0incredible amount of inclusions<\/a>\u00a0stopping light from passing into the diamond.<\/span> Tiny mineral inclusions, including graphite, pyrite or Haematite, spread throughout the stone give the material its black colour.<\/span><\/p>\n\n\n\n

Treated Black Diamonds<\/span><\/h2>\n\n\n\n

Treated diamonds start as natural, low-clarity diamonds.<\/span> White diamonds of very low clarity undergo a treatment process to change the stone’s colour. Technicians colour black diamonds using specific treatments to change the way light reflects from the stone. <\/p>\n\n\n\n

Many treated examples start as grey,\u00a0<\/span>heavily included<\/span><\/a>\u00a0or fractured diamonds and get their colour through a process of high-temperature\/low-pressure treatments. This process d<\/span>arkens the fractures, making them black. <\/span><\/p>\n\n\n\n

The <\/span>treatment of some s<\/span>tones can also produce a green so dark the s<\/span>tone 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.<\/span><\/p>\n\n\n\n
