A diamond is a naturally formed crystal made purely from carbon arranged in a tetrahedral structure, known in gemmology as a crystal lattice.
Diamonds are formed beneath the earths crust by intense heat and pressure, they are brought closer to the surface via magma tubers in the volcanic regions of the earths crust. This means almost all diamonds are found either in or around active volcanic sites.
A sample image of the diamond cubic crystal system showing carbon atoms in a tetrahedral arrangement is shown below:
A diamond is therefore theoretically pure carbon, “C”, and is extremely hard (Moh’s scale of 10, the hardest known mineral to man) because of its structure of carbon. To find a diamond that is pure carbon is rather rare, with less than 2% of all diamonds mined being pure carbon with no boron or nitrogen impurities.
We have been gemmologists registered since 1996 and diamond graders & technologists since 1997, HRD certified diamond grader since 2010, currently we hold the record in our store for the youngest ever gemmologist, diamond grader, diamond technologist and jewellery valuer ever in Australia with a speciality in watches located at the Dymocks building, 428 George St, Sydney, NSW 2000.
