What is the definition of””synthetic diamonds””?
Apply huge amounts of pressure and heat to graphite and you have the recipe for a synthetic diamond. These laboratory-made stones have all the qualities of mined diamonds, but cost much less.HistorySwedish scientists produced the first synthetic diamond at the Allmanna Svenska Elektriska Aktiebolaget (ASEA) Laboratory in 1953. American scientists at General Electric (GE) followed with their own breakthrough in 1955.ProcessMaking a synthetic diamond involves applying 55,000 atmospheres of pressure at 1,400 degrees Centigrade to graphite inside a growth capsule. Some molten iron or cobalt is added to the mix to help speed the reaction. Small diamonds act as “seeds” on which the synthetic diamonds grow.FeaturesIt takes several days for the machine to produce a rough diamond. Lab-made diamonds can range from a quarter carat to 2.5 carats in size. They can be clear or colored. Nitrogen is added in the growth process to produce yellow synthetic diamonds.IdentificationMined and synthetic diam
