Lab Grown Diamonds

What is a lab grown diamond?

Simply speaking, they are just that - diamonds grown in a lab. Grown from tiny carbon seeds, they have the same physical, chemical and optical properties as natural diamonds, but without the environmental impact of the mining process.

A diamond simulant or “fake diamond” is completely different. These are alternative gemstones intended to imitate the appearance of a diamond, for example a Cubic Zirconia or Moissanite. 

How are they grown?

The journey of a natural diamond begins roughly 100 miles beneath the Earth’s surface, facing temperatures of up to 2,200°F and pressure of up to 330 tonnes.

When creating a lab grown diamond we need to try and replicate these conditions within a controlled environment. There are 2 main processes used to create diamonds, ‘High Pressure High Temperature’ (HPHT) and ‘Chemical Vapour Deposition’ (CVD).

Both processes are slightly different, but the end result is the same, to create the high temperature and pressure needed to replicate the natural process within the Earth’s mantel - turning that tiny carbon seed into a stunning diamond. 

How does quality compare?

When talking about the quality of a diamond, it all comes down to the details on a diamond certificate with the colour, clarity, etc. Whether it is a natural or lab grown diamond, they are all graded and certified using the exact same parameters and system.

When it comes to natural or lab grown we use the 3 highest regarded certifications in the industry - GIA, IGI and HRD - and work to the highest standards. The only difference is the certificate will say natural or lab grown.

Why choose a lab grown diamond?

The main advantage of lab grown is cost reduction. Lab grown diamonds are only a fraction of the price of natural diamonds, meaning you will be able to get a far larger size or higher quality for the same price of a natural. 

The environmental impact is another benefit. While natural diamonds are mined from within the earth meaning huge areas must be cleared and mined, a lab grown diamond is created in a controlled environment with very little environmental impact.

Something to bear in mind: in creating lab grown diamonds, a certain amount of energy is needed, but as electricity is moving to renewable sources, this element is becoming increasingly “green”. 

Which is the best choice for you?

This really comes down to the individual. Currently natural diamonds are still the most popular, although lab grown have spike in popularity in recent years.

A natural, mined diamond, may hold more of a romance as it is one of nature’s miracles having been produced over millions of years. However, others may view lab grown diamonds as a ‘human’ miracle, crafted to preserve the environment for the future.

Style preference and budgetary two major factors to consider as you will get a larger lab grown diamond compared to that of a natural diamond at the same price. While quality and optics are no need for concern, there are however issues about whether lab grown diamonds hold their value as well as their natural counterparts.

Are lab grown diamonds real diamonds?

Absolutely! A lab grown diamond has the exact same chemical make-up, hardness, and all other physical and optical properties as a natural diamond. The only difference is a natural diamond is mined from the earth, whereas a lab grown diamond is created by humans in a lab.

Will people be able to tell my diamond is lab grown?

Not unless you tell them. Side by side lab grown diamonds are indistinguishable from their natural counterparts. Even when using a jewellery 10x Loupe, lab grown diamonds are nearly impossible to differentiate from natural diamonds.

What makes them ethical?

The only truly ethical diamonds on the market are lab grown diamonds. If you would like to buy an ethical engagement ring, the only choice is to buy a lab grown diamond. This is one of the biggest reasons that we have chosen to introduce lab grown diamonds as we know the environmental effects mines have on our planet. Approximately 10 square metres of earth is disturbed and almost 3,000 kgs of rock waste are generated for each carat of diamond that is unearthed.

Why are they less expensive?

It’s all about supply and accessibility. The cost of the sophisticated method of producing diamonds in a lab is comparable to the cost of the diamond mining process, Lab Grown Diamonds boast a lower price thanks to accessibility and a competitive market. While the process of cutting, polishing, and obtaining certification also carries a similar cost whether they are mined or lab grown, natural diamonds are severely limited in supply and therefore their price point becomes increasingly inflated as supply further decreases.

Do lab grown diamonds have the same longevity as natural diamonds?

Regardless if they are from a lab or a mine, diamonds are one of the strongest materials known to science. As a result, they are ideal to wear for life and pass on to future generations as they will always hold their beauty.
