If you wish to have a bold and exceptional gemstone, few stand out more than black diamonds. SkyGem & Co. helps you comprehend what you need to know about black diamonds. We have provided updated insights about this striking gem.

What are Black Diamonds?

Black diamonds are a part of the diamond family. But, they differ noticeably in appearance.

Unlike typical colourless diamonds, the deep, rich hue of black diamonds comes from large concentrations of dark inclusions, such as:

  • Graphite

  • Pyrite

  • Hematite

These inclusions absorb light. They give the stone an opaque black or dark grey appearance.

Classic and black diamonds share the same basic chemical composition - carbon. But, they differ a lot in their:

  • Visual effect, and

  • The way they are evaluate

Do Black Diamonds Really Exist?

Yes, black diamonds truly exist. But, the term 'black diamond' may refer to different categories.

  • Natural-colour black diamonds are sometimes called 'fancy black.' They get their colour in nature. They are relatively rare.

  • Many other black diamonds are treated or enhanced to produce the deep black colour.

  • There are also lab-grown black diamonds produced through advanced synthesis.

When purchasing, learn which type you are dealing with. It is because the origin and treatment of diamonds affect value and durability.

Types of Black Diamonds

You can broadly classify black diamonds into three groups:

Natural Black Diamonds

Natural black diamonds are formed naturally with sufficient inclusions or radiation exposure. This is why they appear black.

Treated Black Diamonds

Treated black diamonds were originally grey or lightly coloured. But, they were subjected to heat and irradiation to blacken them.

Lab-Grown Black Diamonds

Lab-grown black diamonds are treated in a laboratory using techniques, such as:

  • Chemical vapour deposition (CVD)

  • High-pressure high-temperature (HPHT) process

To create the colour, lab-grown black diamonds are often treated with intentional:

  • Added defects, or

  • Nitrogen/boron elements

Each type has its own merits and prices. Your preference will depend on:

  • Budget

  • Ethical considerations

  • Preferences
