What is a Lab-Grown Diamond?

A lab-grown diamond is grown in a controlled laboratory environment that replicates the same high pressure and high-temperature conditions that form a natural diamond in the earth with advanced technological processes. These lab-grown diamonds, which still use carbon as their main element, then often require other treatments, such as heat and irradiation, to change the colours and enhance the overall look.

The very first diamond grown in a lab occurred in the 1950s. But, it wasn’t until the mid-2010s, that they entered the commercial jewellery market, once the processes were perfected enough to make it almost impossible to tell the difference between natural and lab-created diamonds.

Our lab-created diamonds are 100% conflict-free, plus they are optically and chemically identical to natural diamonds.

How are Lab-Grown Diamonds Made?

Lab-created diamonds are grown from a tiny carbon seed placed into a chamber of heat and pressure that mimics the natural method of diamond formation. Once the diamond has matured (approximately six to ten weeks), it is then cut and polished.

At Sacet, we grow our diamonds with an advanced technological process called Chemical Vapour Deposition (CVD) , a method by which diamonds can be grown from a hydrocarbon gas.

This process uses ultra-pure carbon-rich gases in a controlled chamber. These gases, a mixture of methane and hydrogen with a ratio of 1:99, are then ionised into chemically active radicals inside the growth chamber. These atoms will then fall onto a diamond substrate and build up layers, getting, as a result, a rough diamond.

Lab-Grown Diamonds vs Natural Diamonds

When it comes to the differences between lab-grown diamonds and natural diamonds, there is no discernible physical, chemical or optical change. Both diamonds have the same cut, colour, clarity, fire and sparkle. Plus, they are both just as tough as each other too. This means you can rely on a lab-grown diamond to be just as durable and long-lasting as a natural diamond.

Both types of diamonds use carbon as their main element, but lab-grown diamonds lack nitrogen which is how gemologists can identify the two. When shopping for diamonds, the easiest way to check whether it’s lab-grown or natural is to check the diamond’s certificate, which all jewellers must have so you know what you’re getting for your money.

What are the Benefits of Lab-Grown Diamonds?

Wondering what the benefits of lab-grown diamonds are? Well, here are our top 4 reasons why you should buy a lab-grown diamond.

  • Eco-friendly:

    lab-created diamonds are grown without negatively affecting native communities or the Earth. The use of water and the amount of land disturbed are also significantly lower during the creation of a lab-created diamond. For example, 18.5 litres are used to create a 1-carat against the 126 gallons of water used for every 1-carat natural diamond.
  • Quality:

    cultured diamonds have the same physical, chemical and optical properties as natural diamonds. Our lab-created diamonds are Type IIa, the purest form of diamond. This type is harder and more brilliant, and only 2% of natural diamonds are of this quality.
  • Value:

    another benefit of lab-created diamonds is that they cost up to 30% - 40% less than natural diamonds.
  • Peace of mind:

    buying lab-created diamonds provides complete peace of mind that a natural diamond cannot guarantee. Lab-grown diamonds are ethically sourced, with no risk of blood diamonds, are environmentally friendly, as they won’t lead to deforestation, and perform identically to the mined variety.

FAQs

Yes, lab-grown diamonds are classed as real diamonds. This is because, unlike other diamond replicas, such as cubic zirconia or moissanite, lab-grown diamonds share the same physical, chemical and optical qualities, score a 10 on the Mohs scale of hardness, exhibit the same fire, scintillation and sparkle and will easily stand the test of time.
It’s no secret that lab-created diamonds have rapidly grown in popularity over the last few years, and many have wondered if they can be worth something if resold at a later date. Though lab-created diamonds have little to no resale value, it’s no different to the resale value of earth-mined diamonds, unless the natural diamond is particularly rare.

You’ll find that it’s almost impossible to sell a natural diamond ring for more than what you originally paid for it. This is because a jeweller, or anyone buying a ring, is highly unlikely to pay for a second-hand diamond at market price when they could buy an identical, new diamond for the same, or lower, price from their trusted wholesalers.

It’s also worth mentioning that buying a diamond engagement ring, whether natural or lab-created, with the intention to sell it in the future is not a good investment - especially as there is plenty of stigma around buying second-hand engagement rings being associated with bad luck.
Just like natural diamonds, lab-created diamonds are unique and will vary in cut, colour and clarity. You may find small inclusions in lab-created diamonds the same as you would in natural diamonds. They are evaluated and graded using the same strict standards by independent gemologists.
Jewellers using the naked eye are unable to tell if a diamond is lab-created or not. As both diamonds are made using carbon, they are almost identical. Even to a trained eye, or with the right tools, such as a loupe, they cannot tell the difference between lab-grown and natural diamonds. The diamond will need to be sent to a specialised gemologist, who will be able to detect whether or not nitrogen is present in the diamond.
As lab-grown diamonds are typically made in larger quantities, using a faster process, they touch fewer hands during production than natural diamonds do. Lab-grown diamonds also don’t need to be transported overseas, which cuts down on shipping costs, and they can be created locally, meaning you’ll also be supporting your communities. Plus, as there is no limit on the supply of lab-grown diamonds, they aren’t as rare. All of this results in a more cost-effective gem. Generally, lab-grown diamonds are between 30-60% cheaper.
