How the Best Lab Grown Diamonds are Made? Posted on June 3, 2019 by Juhi Singh

Laboratory grown diamonds have a similar crystal structure, composition, optical properties, and physical properties as a mined diamond. However, unlike natural diamonds that are made out of the geological processes over thousands of years, laboratory grown diamonds are developed in a laboratory using an arti cial process. Their growth process is also similar to growth of the natural diamonds. The process of making the Best Lab Grown Diamond is one of the most complex and precise techniques that took more than sixty years of efforts to get the right and precise method to grow gemstone quality diamonds. Manmade diamonds are also preferred nowadays as they have the exact similar scintillation, ash, re, and brilliance as mined diamonds. There are typically two methods for lab growing diamond gemstones: High Pressure-High Temperature (HPHT) & Chemical Vapour Deposition (CVD). Each process is suitable for


certain sizes & colors of diamonds. Cvd diamond manufacturers and Hpht Diamonds Manufacturers Surat are engaged making high quality laboratory grown diamonds using different methods.

High Pressure High Temperature High pressure and high temperature is the most widely used process for synthetic diamond. HPHT diamonds manufacturers Surat are engaged in manufacturing lab grown diamonds within massive pressure cookers where small seeds are kept into a growth cell and graphite is insertedon the top of it. Three are typically three press designed used for supplying pressure and temperature to develop arti cial diamonds- the belt press, the cubic press and the split-sphere (BARS) press. These presses can weigh hundreds of tons to produce a pressure of 5 GPa, approximately 70,000 times the pressure at sea level and heated up to 1500°C to make the graphite in the growth cell. It is then melted into liquid carbon and cooled take form of strongest carbon: a diamond crystal. CVD Diamonds CVD diamond manufacturers are engaged in making CVD diamonds grown inside vacuum plasma reactors by using chemical vapor deposition (CVD) method is to grow synthetic diamond from a hydrocarbon gas mixture. This method is simple to set up and make it possible to grow synthetic diamonds over large areas and on different substrates. It does not require as much pressure as the HPHT method as diamond seeds grow through chemical processes under low pressure. The heat is applied to make atomic hydrogen to react with hydrocarbon gas to form pure carbon, which is the diamond. It is primarily used for developing micronsized diamond crystals. These diamonds are cut and polished in the same method as mined diamonds and at the same price as well. They can also be laser inscribed on the girdle so that buyers can identify them as a synthetic diamond. One can look for CVD diamond wholesalers to buy CVD diamonds at the best prices in the industry and of course, these are far cheaper than natural stones. Many Hollywood celebrities are also nowadays promoting the best lab grown diamond as the techniques are more environmentally friendly and sustainable than natural stones. These diamonds are long-lasting, easy to use for various purposes, ne nishing, lightweight, attractive pattern and superior quality.
