How are lab created diamonds grown
 GIA)
WebLab-created, lab-grown, or synthetic diamonds have the same optical, physical, and chemical properties as their mined counterparts. The only significant difference between a lab-created and mined diamond is that one forms in a controlled environment in a laboratory, and the other forms over time in the uncontrolled environment of the Earth. They’re generally grown using a high-pressure, high-temperature (HPHT) method. Scientists at General Electric designed the first HPHT method in 1954 to mimic diamond growth deep below the Earth’s surface. HPHT is the most economical process for growing large diamonds. Ver mais The HPHT process begins with a tiny diamond fragment, known as a seed crystal. This is placed in a cell inside a press, together with a … Ver mais The press heats the cell to a searingly high temperature, up to 1,600°C. It then uses metal anvils to apply intense pressure. The pressure and temperature need to be high enough to melt the metal catalyst. Ver mais After the diamond has been cooled, it’s ready to be cut and polished, just like nature’s finest. It can then be graded for cut, colour, carat and … Ver mais The molten metal carries carbon atoms from the graphite to the seed crystal. The carbon atoms slowly build up around the crystal to give the … Ver mais
