So what are Lab Grown Diamonds?
Simply put, a Lab Grown Diamond is a diamond which has been grown in a laboratory instead of bring mined from the Earth. Chemically identical to a Natural Diamond, a Lab Grown Diamond is created in the same conditions. There are two methods of creating Lab Grown Diamonds, we’ll have a look at each separately below.
The HPHT – Hight Pressure High Temperature – method replicates the natural process of Diamond formation underneath the Earth’s crust, like a giant pressure cooker.
💎 Pure carbon is pressed within a metal cube and exposed to immense heat and pressure through electric pulses.
💎Eventually the carbon breaks down and crystallises into a Diamond.
The way Diamonds are formed is often a comfort to me in times of stress, I remember that when carbon is put under extreme pressure it turns into something rare and beautiful.
CVD – Chemical Vapour Disposition – superheats gas into plasma releasing carbon atoms to ‘build’ a diamond crystal at the atomic level.
A thin slice of diamond, around 300 microns thick and 10x10mm, known as a ‘diamond seed’, is selected, thoroughly cleaned and placed in a sealed chamber.
💎 The chamber is heated to around 800°C and flooded with carbon rich gas.
💎 The gas ionises, breaking down into pure carbon
💎 The pure carbon molecules attach to the original diamond seed
💎 This process continues until a fully formed diamond is created
Are Lab Grown Diamonds real Diamonds?
The short answer is yes. Lab Grown Diamonds are real diamonds. Even under magnification, an experienced gemologist may struggle to differentiate between a Natural Diamond and a Lab Grown Diamond.
Lab Grown Diamonds are not ‘fakes’. As I mentioned above, they are chemically identical to natural diamonds. The technical difference is that they aren’t millions of years old. Using the methods above, they can be created in between 1-4 weeks. Once grown, they are polished with the same tools and brought to market in the same manner as natural diamonds.
Specialist equipment is needed to determine if a diamond is natural or lab grown.
Do Lab Grown Diamonds look the same?
Yes, in casual viewing Lab Grown Diamonds are identical to Natural Diamonds. An experienced jeweller or gemologist may, under a loupe, be able to identify characteristics which point to a Lab Grown origin but when worn they are indistinguishable from Natural Diamonds.
Are Lab Grown Diamonds Graded in the same way as Natural Diamonds?
Yes. Lab Grown Diamonds and Natural Diamonds are all graded using the ‘four c’s’ which are Carat, Colour, Cut & Clarity.
Are Lab Grown Diamonds less expensive?
Yes. Lab Grown Diamonds are a lower price than a comparable Natural Diamond.
Which is better, a Lab Grown Diamond or a Natural Diamond?
Neither Diamond is a ‘better’ choice, as with all jewellery it depends on what is most important to you. If you would like someting of a natural origin that has the history and story of being in the Earth then a Natural, Earth Mined Diamond is a good choice. If price is an important factor then a Lab Grown Diamond may be better for you.
