With the influx of diamond references in popular culture from Diamonds are Forever, the seventh film in the James Bond series, to musician Rihanna’s hit single Diamonds and Kanye West’s highly acclaimed song, Diamonds From Sierra Leone, it’s no wonder why diamonds are constantly on our minds.

However, when it comes to buying a diamond, we understand it can be a bit tricky. Should you go with a natural or lab grown diamond? While the choice is completely up to you, this blog post will help dispel some of the myths behind natural and lab grown diamonds, helping you make a more sound and informed decision. It will also provide you with more information on how long it takes to make a lab grown diamond. 


How long does a lab grown diamond take to make?

Unlike natural diamonds, which are formed beneath the Earth’s surface under extremely high pressure and heat over millions of years, lab grown diamonds roughly take about six to ten weeks to be create.


How long does a lab grown diamond take to make using the CVD method?

Before we go into the manufacturing process of a CVD diamond, I think it’s best we first explain what a CVD diamond is.

In short, a CVD diamond is an acronym for a lab grown diamond which is created using the Chemical Vapour Deposition method. This method involves inserting a small diamond seed crystal into a sealed vacuum and subjecting it to high pressure, temperature and gas. By adding the gas ,(often methane) and subjecting it to high pressure and temperature,  the gas’ carbon atoms are broken down. This results in these atoms latching on to the diamond seed crystal to form more crystals. This process then eventually creates a diamond.

A diamond created using the CVD method is almost identical to one made naturally. It also usually takes about a month or so to make a 1 carat CVD diamond.


How long does a lab grown diamond take to make using the HPHT method?

This term  is simply an acronym for a diamond that is created using the High Pressure and High Temperature method – hence “HPHT”. 

HPHT was one of the first methods used by scientists to create lab grown diamonds in the 1950s, and  it involves simulating the method of natural diamond production. This process is carried out by placing a carbon material, such as graphite with  a metal catalyst such as iron, nickel or cobalt and exposing it to extremely high pressure and temperature to form diamond crystals.

So how long does a lab grown diamond take to make using the HPHT method? It can take anywhere from a few days to a few weeks to grow several crystals. Then to grow a 1 carat diamond using the HPHT method, it takes about a fortnight.


Pros of lab grown diamonds

Now that you’ve got an understanding of how long it takes for a lab created diamond to be made, it’s time to discuss their advantages and disadvantages.

You know their origin

One of the biggest advantages of lab grown diamonds is the fact that you can be almost 100 per cent certain of their origin. While most people are vigilant in ensuring their diamonds are free from conflict, you can feel assured that with lab grown diamonds, they did not contribute to child exploitation or war.

The price

Another major benefit of lab grown diamonds is their price. When compared with natural diamonds, lab grown diamonds of the same size, clarity and cut, can be at least 20 percent cheaper than their natural counterparts.

More environmentally friendly

Lab grown diamonds are also more environmentally friendly when compared with natural diamonds. Though the specifics are unclear as to how much more sustainable lab grown diamonds are, the University of Delaware Energy and Environment Professor Dr Saleem Ali told media outlet, JCK “on the environmental side, there is no question that synthetic diamonds will be less impactful than mined diamonds.”

They’re fashionable

Lastly, if you’re all for becoming a trailblazer in the fashion scene, opting for a lab grown diamond over a natural diamond can illustrate your impeccable taste as well as your conscious mind. This notion is further supported by a study conducted by Vogue in May 2021, which found that 69 percent of its audience stated sustainability is an important factor when making a fashion purchase.

Coloured diamonds are easier to make

While naturally coloured diamonds are often rare, difficult to find and a great deal more expensive than traditional colourless diamonds, synthetic coloured diamonds are not only easier to manufacture in a wide range of colours but come at a significantly cheaper price point. Which means you can easily find a stunning lab grown coloured diamond ring to suit your budget!


Cons of lab grown diamonds

There really are very few cons when it comes to lab grown diamonds. The main detriment associated with lab grown diamonds is the loss of the ‘it factor’ commonly associated with diamonds. While natural diamonds are unique and are almost always ‘a one of a kind’ treasure, lab grown diamonds are seen to be without this allure because they are manufactured in bulk. In saying that, there are still so many benefits of lab grown diamond jewellery, which means they’ll be treasured for years to come!

To buy a lab grown diamond or not?

We’ve given you the facts but ultimately the decision to purchase a lab grown diamond over a natural diamond is up to you. Generally, if you don’t mind forgoing the history, rarity and resale value of natural diamonds then a lab grown diamond may be for you.

It’s not an easy choice to make so we urge you to take your time and consider your priorities first. If lab grown diamonds are your final pick, then be sure to check out our range of lab grown diamond engagement rings, lab grown diamond earrings and other jewellery! We’re confident you’ll be more than just delighted.

How long does a lab created diamond last?

Lab diamonds really do last forever, and there's nothing that will dull the shine or interfere with the brilliance of synthetic diamonds.

Is it expensive to make lab grown diamonds?

It is said cost around $300 to $500 USD per carat to produce a CVD lab-grown diamond, compared with $4,000 USD per carat in 2008. As lab grown diamonds become cheaper to produce, they become more affordable for buyers.
