All you need to know about diamonds

As one of the most beautiful and rare materials on the planet, humans have long been fascinated by diamonds. A symbol of enduring love and timeless quality, diamonds are undeniably special. But what makes them so special? And how do you know what to look for when choosing the perfect diamond engagement ring?

History and romance

We’re not the first generation to love diamonds, our infatuation with these beautiful stones has a long and romantic history.

Diamond history

The Ancient Greeks believed that diamonds were shards of fallen stars. In India, meanwhile, early Hindus believed diamonds were created by lightning striking the Earth. While the Romans thought they were teardrops from the Gods.

Today we know much more about how they're formed. And though it’s a less romantic story, diamonds are still considered as beautiful and intriguing as ever.

How diamonds are made

Natural diamonds are a type of mineral made up of carbon atoms. Because of how diamonds are formed, every diamond on Earth will be at least a billion years old, if not a couple of billion. They come in a variety of colours, from yellow to brown, and even pink, although the most commonly found in jewellery is white.

Coloured diamonds

Forged deep underground, they’re made under immense heat and pressure. Making them the hardest known natural substance on the planet. The origin of the word ‘diamond’ is adámas, meaning unbreakable, which is why they have come to be associated with unbreakable, everlasting love.

How are diamonds made in a lab?

Nowadays we’re also able to make diamonds in laboratories. By recreating the same intense conditions, scientists can create lab-made diamonds. These are real diamonds and identical to natural diamonds in every way (except their age, obviously!) Lab grown diamonds are becoming increasingly more common, although they tend to be less valuable than natural stones.

How are diamonds graded? Diamond quality explained

The quality of a diamond is determined by four factors. These are commonly known  as ‘the four Cs.’ The four Cs of diamonds are colour, cut, clarity, and carat weight.

The 4 Cs of diamonds
They are what jewellers use to determine the value of each diamond and how to price each diamond.


The colour of a diamond is graded on a scale from D to Z, with D being the most colourless and Z being the most coloured.


The cut of a diamond refers to the way that the diamond has been shaped. A well-cut diamond will reflect light beautifully, while a poorly cut diamond will be dull and lifeless. Some think this is the most important factor when determining a diamond’s quality.


The clarity of a diamond refers to the number and size of inclusions, or flaws, in the diamond. The fewer inclusions a diamond has, the more valuable it will be.

Carat weight

The carat weight of a diamond refers to its weight in grams. The larger the carat weight, the more valuable the diamond will be.

Diamond engagement rings

A diamond engagement ring is forever. A timeless classic that will never age. But how do you choose the right ring for you, or your intended?
