Product Description

what is synthetic (lab grown ) diamond ?

Synthetic diamond (also known as laboratory-created diamond, laboratory-grown diamond, cultured diamond or cultivated diamond) is diamond produced in an artificial process, as opposed to natural diamonds, which are created by geological processes. Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively).

 HPHT (High Pressure High Temperature) diamonds

The HPHT (High Pressure High Temperature) Diamonds mimics the way diamonds are produced naturally deep inside the Earth's crust. Special machines are used to build up the pressure of almost 60,000 atmospheres and temperatures of 2,500 degrees Celsius to start with the growth of HPHT diamonds. Special growth cells which contain elements needed for growing a diamond like highly refined graphite and a catalyst mixture consisting of metals and powders are planted into the HPHT chamber where consistent temperature increases up to 1,300 Degrees Celsius and more than 50,000 atmospheres of pressure is applied. The catalyst inside the cells transforms the cells from solid to molten form.
Within a few days and after a few conditions are met, the cooling process begins. This takes a few days and allows the carbon atoms to build on the atom seed. The cell is removed from the HPHT machine only when it is deemed to be sure that the growth cycle has been completed.

The new rough HPHT diamond is then extracted and cleaned for the final cutting and polishing.

HPHT diamonds are then polished in similar way as that of Mined Diamonds along with other manufacturing processes. These Lab Grown Diamonds are used for both industrial as well as Gems & Jewelry sector.

Why synthetic (lab grown) diamond ?

1.Types of synthesized diamonds are increasing and their quality is being perfected.

2.Synthesized diamonds possess not only the perfect diamond 4C standard, but also plentiful, changeable colors and diamond fire colors

Why synthetic (lab grown) diamond ?

3.Synthesized diamonds possess both the decorative practicability of jewelry accessories and the physical properties of the natural diamonds.

4.Synthesized diamonds far excel the natural diamonds as to the technological hurdles and scientific cost.
But their retail prices are lower than those of their natural counterparts
