FEATURED ARTICLE WHAT ARE SYNTHETIC DIAMONDS? BY KAYLAN KHOURIE, FGA The author of this article is a FGA qualified gemmologist and laboratory gemmologist at EGL South Africa. This article aims at aiding those in the diamond and jewellery industry with regards to synthetic diamonds. A diamond is a mineral made up of essentially crystallized carbon. They occur naturally and can be grown in a laboratory using two methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods imitate the environment within which natural diamonds grow, in order to grow diamond onto a seed plate (made of a thin slice of diamond - either natural or synthetic).

As the mixture cools down, the carbon low pressure. Within this chamber, methane (a carbon and crystallises onto a seed plate within the chamber and the hydrogen gas) is irradiated by microwaves that form a plasma synthetic diamond begins to grow. cloud around seed plates. These seed plates are on top of a platinum base that gets heated up to a very high temperature. (Shigley, 2016 - Identifying Lab-Grown Diamonds). During this process, carbon is separated from the gas and HPHT synthetic diamonds can be grown as a vivid yellow deposited onto the seed plates and the diamond is grown. colour (caused by nitrogen), but by adding ‘nitrogen-getters’ CVD synthetic diamonds are usually grown as a brownish or into the chamber during growth, colourless diamonds can greyish colour (Figure 3) and are often treated afterwards in be created.

Photo by author Terminology Figure 6: A ‘False natural’ on a bruted girdle of a synthetic diamond. Photo by author • The following terms are acceptable to refer to diamonds that are grown in a laboratory: “Synthetic”, “Laboratory- grown”, “Man-made” or “Laboratory-created”. • The following terms are not acceptable to refer to diamonds that are grown in a laboratory: “Cultured”, “Eco-friendly” or “Manufacturer name-diamond”. • A “simulant” is a gemstone that imitates diamond but does not have the same chemical, physical or optical properties – for example cubic zirconia, YAG and synthetic moissanite. Full disclosure that a diamond is laboratory-grown is extremely important to ensure consumer confidence. Common misconceptions regarding synthetic diamonds COMMON MISCONCEPTION CORRECTION “Synthetic diamonds are not real\" Synthetic diamonds have the same physical, chemical and optical properties as natural diamonds; its durability, brilliance and lustre is superior to the common simulants of a “Diamond testers can separate natural and diamond. Synthetic diamonds are real diamonds; they have just been grown in a laboratory synthetic diamonds\" instead of being grown by natural processes. “Scratch pens can be used to detect Diamond testers use thermal and electrical conductivity to separate a diamond from synthetic diamonds” its simulants. Because synthetic diamonds have the same physical properties as natural diamonds, they have the same thermal and electrical conductivity levels “Polished synthetic diamonds are not commercially as natural diamonds; therefore, a diamond tester cannot separate a natural from available larger than 1 carat” a synthetic diamond. “Synthetic diamonds are only created in the Scratch pens are made with (usually) a synthetic corundum tip – with a Mohs hardness colourless range” of 9. The scratch pen cannot scratch a diamond as diamonds have a Mohs hardness of 10 – the pen can only scratch stones with a hardness of 9 or less. Because synthetic “Synthetic diamonds only have faceted girdles and diamonds have the same hardness as natural diamonds, a scratch test cannot cannot have ‘naturals’” separate the two. Synthetic diamonds come in sizes from melee up until very large sizes. At the time of writing, the largest grown gem-quality HPHT synthetic diamond reported is a 15.32ct cushion-shaped diamond (Magaña & Ardon, 2018) and the largest grown gem-quality CVD synthetic diamond reported is a 9.04ct round diamond. (WD Lab Grown Diamonds, 2018). Synthetic diamonds can be grown in various colours. The colours that cannot be achieved by the growth process can be done so by post-growth treatments (such as irradiation, annealing, HPHT treatment, LPHT treatment or a combination of these treatments.) – See Figure 2. ‘False naturals’ can be carved onto the girdles of synthetic diamonds and they can also be cut to leave a small part of the synthetic rough skin on the girdle that can imitate the look of ‘naturals’ found on naturally grown diamonds (See Figure 6). Synthetic diamonds can be found with bruted, faceted or polished girdles. PAGE 33
