Here at Quality Diamonds, we are pleased to be able to offer both Natural and Lab Grown Diamonds to our customers, giving you the option of choosing which Diamond is perfect for you.

Our Lab Grown Diamonds are currently not available on our website, so for any questions or enquiries please feel free to contact our Diamond experts; who are available through email, telephone, live chat, or by booking an appointment.

For those of you who want to know more about man-made Diamonds, below we've answered some questions that will give you an insight into what Lab Grown Diamonds are. 

What are Lab Grown Diamonds?

Lab-Grown Diamonds are created in a highly controlled laboratory environment that uses an advanced technological process, in order to duplicate the conditions in which diamonds naturally develop beneath the Earth. They can also be known as Engineered, Lab Created, Man-made, or Cultured Diamonds; though they are often mistakenly referred to as ‘synthetic’ diamonds, this term may be a big reason why people think Lab-Grown Diamonds are fake.

These Diamonds are made of carbon atoms that have been arranged in a characteristic diamond crystal structure. As the Diamonds are made of the same material, they are able to hold the same chemical properties and optical display.

How are they made?

Lab Grown diamonds are made from carbon seeds of natural Diamonds. The Diamonds are formed within a lab, using a process that mimics the method in which natural Diamonds are formed. This is through extreme pressure and heat, or a special deposition process.

Can you tell the difference?

As these Lab Grown Diamonds are created in a way that portrays their natural formation, it is hard to distinguish Natural vs Lab. The only way is through specialised lab equipment, that can detect any minor difference in the crystal growth of the Diamond. Additionally, the composition of trace elements within lab-grown diamonds may differ from a natural Diamond.

What are the benefits of a Lab Grown Diamond?

  • Lab-Grown Diamonds offer an incredible value, as they are more affordable than their natural Diamond counterpart when comparing size and quality. They can be anywhere from 20-30% less expensive than mined diamonds: skipping the mining process results in a shorter supply chain, in simple terms, it touches ‘fewer hands’ making them ultimately less expensive.
  • As they are made in a laboratory, they are ethically grown and produced in a sustainable way, reducing the environmental impact.
  • Lab-Grown Diamonds have the same physical appearance and are both chemically and optically the same as natural diamonds.

Prices are for Round Brilliant Diamonds and are correct as of May 2021. Prices are subject to change.


Does that mean the Natural Diamonds you sell are not ethical?

No. The Natural Diamonds that we supply are all ethically sourced and have been passed through the Kimberley Process, in order to ensure their authenticity.

The mining of Natural Diamonds has helped towards benefiting and improving the living conditions of many countries. See more about our conflict-free diamonds here.

Do they still come with a Certificate?

Yes. Lab-Created Diamonds are still certified by many of the leading gemological laboratories. The Lab-Grown Diamonds that we supply at the moment are mostly certified by IGI, and state on the certificate that they are Lab Grown. The only other company that we would supply Lab-Grown Diamonds is GIA, though they’ve only recently announced this service: both of these are well respected Diamond Certification Companies. See below an example of a Lab-Grown report.

How are Lab-Grown Diamonds Certified and Graded?

Lab-Grown Diamonds are graded the same way natural diamonds are: they are sent to a gem lab, like GIA and IGI, where they grade using the 4C’s. (LINK)

Each diamond is graded individually by multiple gemologists at the lab, these grades are then compiled and analysed to determine their final grade report. This method creates unbiased results.

Is a Lab-Grown Diamond the same as a simulant?

No. A diamond simulant, such as cubic zirconia, has been man-made to look similar to diamonds, but are not made from carbon crystals. The chemical and physical properties are not the same and are therefore available at a much lower price point. Simulants are easily distinguishable by eye.

So should I choose a Lab-Grown Diamond or a Natural Diamond?

This part is up to you, and quite often comes down to personal preference.

Whilst Lab-Grown Diamonds have added benefits with no physical difference, the beauty and story of a Diamond that was formed millions of years ago beneath the earth's surface, still holds it’s impressive history.
