A Tale of Two Diamonds

Diamonds: Earth Mined v Laboratory Grown – The Facts.

Everything you need to know about diamonds – earth mined and laboratory grown.

Patrick Wyatt Jewellery Diamonds

Spot The Difference.
A laboratory grown diamond is essentially identical to a mined diamond. Made of carbon, each has the same physical and chemical properties – such as light refraction and chemical structure. A laboratory grown diamond, IS a diamond – not a diamond substitute, such as Cubic Zirconia or Moissanite.


Laboratory Grown Diamonds

Ethical & Environmentally Friendly.
The origin of a laboratory grown diamond is 100% traceable, which guarantees each one is ethically sourced and eco friendly. Laboratory grown diamonds are cultivated in a controlled environment, thus incurring a smaller carbon footprint, are conflict-free and produced with respect to human rights.

Generally speaking, laboratory grown diamonds cost approximately 20% to 30% less than mined diamonds, which means you can purchase a superior stone for the same price.


Mined Diamonds

Where Are They Found?
Diamonds are found on almost every continent. The five major diamond mining countries are: Russia, Democratic Republic of the Congo, Australia, Canada and Botswana. There are plenty elsewhere, such as Brazil, Angola, South Africa and Namibia. It is thought that Russia has the greatest reserves of diamonds.

Lab Diamonds vs Earth Mined Diamonds

How Are Diamonds Graded?

The Four Cs
Earth mined, and now laboratory grown diamonds, are graded and categorised by the diamond industry using the four characteristics which are considered the most important in determining the value, rarity and beauty of a diamond.

Cut: The cut refers not only to the shape but also the amount of brilliance and sparkle in a diamond; how well it is proportioned. Grades range from ‘Excellent’ to ‘Poor.’

Clarity: The clarity grade measures inclusions – naturally occurring marks formed with the diamond, over hundreds of millions of years. Marks can appear on laboratory grown diamonds too, as the lab process mimics how naturally earth mined diamonds are created. The scale ranges from ‘Flawless’ to ‘Included’.

Colour: In most diamonds, the term actually refers to the absence of colour. The less colour in the stone, the more desirable and valuable. The D grade, at the top of the scale, is considered ‘Colourless’, rarest and most expensive. As the scale ranges from D to Z, diamonds become progressively more yellow, brown or grey.

Carat: This refers to the weight of a diamond – generally, the higher the carat, the more expensive the stone. Two diamonds of equal carat weight, can be very different in terms of quality and price, when the other three Cs are considered.

Which shapes and cuts are most popular with your clients?

Patrick: Modern round brilliant and emerald cut.
Geoff: Whilst the round will always be the most popular shape, other less usual cuts have their day too.  Cushion cuts for example are popular.


Which precious metal would you recommend for diamonds?
Platinum! It is the king of metals.  Not always easy to work with but the choice for a piece of jewellery designed to last many generations.  The vast majority of our clients choose platinum.


Famously worn by…
Two Elizabeths – Taylor and Queen Elizabeth II. Whoever wears diamonds, will be in good company.

The long and short of it.
Whether a diamond is earth mined or laboratory grown, this is not the most important thing.  A piece of jewellery represents love or commitment.  You don’t have to be a superstar or royalty to be the recipient of those.
