So, what is a Lab Grown diamond?

Lab Grown diamonds are created in controlled environments, utilising advanced technology to replicate the natural processes that occur deep within the Earth. This process results in diamonds of exceptional quality and beauty, boasting the same mesmerising brilliance as mined diamonds - without the human and environmental toll of mining.

Lab vs mined?

With the same physical, chemical and optical properties, the only difference between lab and mined diamonds is their origin. Both types of diamonds sparkle in the same way for they are crafted from the very same element - pure carbon. Not to be confused with diamond simulants like cubic zirconia, which are created with different materials.

Lab diamonds are so remarkably similar to their mined counterparts that even trained gemologists find it difficult to differentiate between the two without specialised equipment that can detect minor differences in trace elements and crystal growth.

Are Lab diamonds real diamonds?

Lab diamonds are indeed real diamonds, as genuine as those mined from the earth. The clear distinction lies in their origin – ethical diamonds are created in a laboratory, while mined diamonds are extracted from the earth’s crust through mining operations. The US Federal Trade Commission (FTC) made the landmark ruling that a diamond is a diamond whether it comes from a lab or the ground, in 2018.

Both lab and mined diamonds:

  • Are made of the same mineral, carbon, and share the same DNA
  • Measure 10 on the MOHS scale of hardness.
  • Grown in their own way with one of a kind inclusions and patterns.
  • Are graded in the same way - in accordance with the GIA’s 4 C’s - Clarity, Cut, Colour and Carat.
  • Come with certification and an inscription on the girdle to identify the diamond - the GIA (Gemological Institute of America) has been grading lab diamonds since 2007.

Benefits of Lab diamonds?

By harnessing cutting-edge technology, lab-created diamonds eliminate the need for expensive mining practices while enhancing the precision of cutting and polishing. As a result, these diamonds are priced at a fraction of the cost of mined diamonds—typically 30-50% less. This affordability allows clients to indulge in larger diamonds that fit their budget without compromise. Embrace the financial advantages of lab-created diamonds.

How are Lab diamonds made?

Lab-grown diamonds are produced through two distinct methods: chemical vapor deposition (CVD) and high pressure, high temperature (HPHT). In the chemical vapor deposition process, a diamond seed is exposed to a gas mixture, resulting in the gradual accumulation of carbon atoms and the formation of a flawless crystal structure.

Conversely, the high pressure, high temperature method replicates the natural conditions found deep within the Earth’s crust, where diamonds are naturally formed. This enables the cultivation of lab-grown diamonds with exceptional clarity and brilliance. Most importantly, they sparkle with the same brilliance as mined diamonds because they are made of the same substance: carbon.

How Long Does It Take To Grow Lab diamonds?

The duration required to grow Lab diamonds varies depending on the desired size and quality. In general, the process can take anywhere from a few weeks to a few months. The growth process involves creating the right conditions for the carbon atoms to accumulate and form a crystal structure. This includes maintaining specific temperature and pressure levels.

The intricate nature of growing diamonds requires careful monitoring and precise control. Despite the time investment, the end result is a beautiful and sustainable diamond that exhibits the same brilliance and clarity as mined diamonds.

Do Lab Diamonds Test Positive As Diamonds?

Yes, a Lab diamond will test positive on a diamond tester. These diamonds are identical to mined ones, passing every test for authenticity.

Created by scientists, ethical diamonds possess the same chemical, physical and optical properties. Even expert gemologists struggle to differentiate them visually. Only specialised equipment reveals subtle distinctions in trace elements and crystal growth.

Lab diamonds are the real deal, indistinguishable from mined diamonds.

Which Celebrities And Brands Are Using Lab Diamonds?

As the popularity of Lab diamonds continues to rise, more and more celebrities are choosing to wear these these gems - without the human and environmental toll of mining.

High-profile figures such as Drake, Anna Wintour, Rihanna, Lady Gaga, Zendaya, Emma Watson, Jennifer Hudson, Meghan Markle and Leonardo DiCaprio have been seen proudly sporting lab-grown diamonds at red carpet events and in their personal lives.

Luxury brands Prada and Fred have recently released fine jewellery collections with lab diamonds, while Breitling and Tag Heuer are utilising lab diamonds in their watches, along with an increasing number of luxury brands including Balmain, Gucci and Jean Dousset, the great grandson of Louis Cartier - who created a business that solely utilises lab grown diamonds in his jewellery. Dousset says his great grandfather would have certainly understood the switch because he was an innovator.

Can You Tell a Lab And Mined Diamond Apart?

The truth is that not even jewellers and gemologists can tell the difference between mined and Lab diamonds with the naked eye. Both types of diamonds share the same physical and chemical properties, including their exceptional brilliance and hardness. However, gemologists can use specialised equipment to distinguish between the two.

For example, lab diamonds often have unique growth patterns or small inclusions that are characteristic of the growing process. Overall, without the use of advanced testing methods, it is nearly impossible to visually differentiate between ethical and mined diamonds.

Can Lab Diamonds Be Insured?

Yes, similar to mined diamonds, Lab diamonds can be insured. Speak to our design director for further information.

Does The Cut Jewellery Work With Mined Diamonds?

At Cut Jewellery, we proudly work with Lab diamonds. However, if you would like us to create one of our special pieces with mined diamonds, we’re more than happy to. After all, a diamond is a diamond! Craig has been sourcing mined diamonds for many decades. Contact our design team to inquire.

Can I Choose Any Shape With a Lab Diamond?

Both mined and Lab diamonds can be cut into a variety of shapes and forms.

One of the most prevalent shapes for Lab diamonds is the round diamond, which is known for its exceptional brilliance. Referred to as the round brilliant cut, it is highly sought after and commonly chosen for both lab-created and naturally mined diamonds.

Any shape other than round is classified as "fancy” and are available in lab-grown diamonds including; Emerald, Pear, Asscher, Marquise, Cushion, Heart, Oval and Radiant.

Is a Lab Diamond Synthetic?

Lab diamonds are not simulants, in fact they are made of the same mineral as mined diamonds - crystallised carbon. Not to be confused with simulant diamonds such as cubic zirconia or other simulants which can chip with regular wear.
In contrast, Lab diamonds exhibit the same durability and brilliance as natural diamonds, with none of the shortcomings associated with imitations.

Do Lab Diamonds Come With Certification?

Yes, Lab diamonds are subject to the same rigorous grading procedures as their mined counterparts. Established diamond grading labs, such as the Gemological Institute of America (GIA), IGI, ECL, and GCAL, offer grading services specifically for lab-grown diamonds.

Certification is crucial when purchasing ethical diamonds. It is strongly advisable to only acquire diamonds that have undergone certification, regardless of their origin. The grading process, which considers the 4Cs (carat weight, cut, color, and clarity), plays a vital role in determining the quality and value of the diamond. This ensures that consumers make informed decisions and acquire diamonds that meet their desired specifications.

Will Lab Diamonds Last?

Lab diamonds possess the same chemical and physical properties as mined diamonds. They are the hardest mineral known to man and measure 10 on the MOHS scale of hardness. With proper care, lab grown diamonds will maintain their brilliance and beauty for generations to come, making them a timeless and sustainable choice for those seeking enduring elegance.
