Diamond – The Beauty of Diamond Have you ever own a piece of diamond or diamond Jewelry? Do you know where are they coming from and why are they so valuable? Let’s have a journey to expose the nature and secret of diamond. Atomic structure & physical property Do you know diamond is actually carbon, sharing the same element with graphite? Diamond is an allotrope carbon. A carbon atom is connected to 4 other carbon atoms to form a tetrahedral 3 dimensional structure. It is the hardest natural elements known in the world. As well, diamond is has the highest thermal conductivity. This is the reason why diamond is used as main components in the cutting and polishing tools. During the normal cutting process, huge amount of heat are generated in a very short period of time, if heat is not transmitted away immediately, the tools will be over-heated and damaged. Since diamond is hard, it’s good for cutting, it has high conductivity transmits heat away in very short period of time, it makes diamond an excellent component for cutting dies. Diamond as a gemstone Diamond has high optical dispersion. This makes diamond a beautiful luster as it effectively disperses lights of different colors that we commonly called it fire and sparkle. High optical dispersion, great mechanical properties, combined with its scarcity makes diamond a very valuable gemstone. Besides, diamond jewelry is suitable for daily wear as it has high scratch resistant and is also good to wear in nearly all occasion. Can diamond be synthesized? Scientists suggested diamonds are naturally produced at high temperature and pressure hundreds of miles down underground. It’s possible to produce diamond in laboratory, however the cost is super-high and so, it is worth to own a piece of diamond or diamond jewelry. Diamond Supply Annually there is around 60,000 pounds of diamond are mined, and about 200,000 pounds of diamond are synthesized. About half of the world jewelry is supplied by Central and South Africa. Others are mainly supplied from Canada, India, Russia, Brazil and Australia. Have fun!
