Man Made Diamonds also known as engineered or cultured diamonds, are grown in a scientifically controlled laboratory environment using advanced technological processes duplicating conditions thousands of kilometers below the surface of the earth.
Natural diamonds develop in the mantle, beneath the Earth’s crust.
Our Laboratory created diamonds which are 100% pure carbon atoms in the diamond crystal structure, are created in the same way using laboratory equipment.
Our lab diamonds are grown from the tiny carbon seeds of per-existing natural diamond.
Advanced technology using either extreme pressure and heat or a special deposition process replicates the natural method of diamond formation.
HPHT or High Pressure High Temperature method
Using one of three methods a Belt press, Cubic press and the Split-sphere or BARS press.
Diamond seeds are placed at the bottom of the press.and heated above 1400 °C.
High purity carbon source is dissolved, which is then precipitated to the small diamond seeds and, forming a synthetic diamond crystal.
Chemical Vapour Deposition CVD diamond growth inside a vacuum chamber filled with a carbon gas.
A source of microwave energy breaks down the gas molecules.
The carbon atoms are then attracted to flat diamond seed placed in the machine where the diamond begins to grow.
Despite the difficulty in identifying these stones by conventional means,
GIA researchers did find unique spectroscopic signatures.
They did so by subjecting photoluminescence and ultraviolet fluorescence reactions to the DiamondView™.
A sophisticated instrument used by gemological labs to detect synthetic diamonds.
