How are lab grown diamonds created?


How are CVD Diamonds made?
A small numberious tiny pieces of diamond,called seeds, are heated to
around 800°C in a sealed container before being
filled with other carbon-rich gases, such as methane.
Microwaves, lasers and other devices are then used to
ionize the gasses and create plasma. The breakdown of
the gasses by ionization allows the carbon to merge with
the diamond seed and grow the diamond layer by layer.

Lab grown diamonds are identical to natural diamonds in
every way, but they are created in a controlled environment using
cutting-edge technology rather than deep below the earth's surface.

The two main procedures commonly used to create lab grown
diamonds are High Pressure High Temperature (HPHT) and Chemical
Vapor Deposition (CVD). Both methods simulate the earth's natural processes to create beautiful diamonds in a strictly managed
laboratory setting.

igh Pressure High Temperature Method (HPHT)

The high-pressure, high-temperature (HPHT)
diamond production process was first developed
for industrial use in the 1950s. While it is most
commonly used for creating lab grown diamonds, mined
diamonds can also be treated using the HPHT procedure
to improve their clarity and color.

HPHT diamonds are produced using three fundamental
manufacturing techniques: the split-sphere (BARS)
press, the cubic press and the belt press. A small
diamond seed enclosed in pure carbon is placed into
a growth chamber subjected to a high-pressure and
temperature environment for several days. Then, as
the carbon melts, a diamond is formed around the seed until a
full-sized gem develops.


Chemical Vapor Deposition (CVD)
During the CVD process, a diamond is created from a hydrocarbon
gas mixture, similar to how interstellar gas clouds produce
diamonds. The procedure developed in the 1980s is widely
seen as the less expensive way to make diamonds because
it uses less energy than HPHT.

In Short:
Have essentially the same chemical, optical and physical properties and crystal structure as natural diamonds.
Are made of tightly-bonded carbon atoms.
Respond to light in the same way and are just as hard as natural diamonds.
Are created from tiny carbon seeds of pre-existing diamonds using advanced technology such as extreme
pressure and heat or
chemical vapor deposition.
Are chemically, physically, and optically identical to natural  diamond and  chemically, physically, and optically identical to natural 
diamonds, and have the same famous Mohs hardness of 10.

The only difference is Lab diamonds are more brighter and luminous than natural diamonds.

Price:  concededly less in price than diamonds.

Example a 5ct diamond may coast $5,000. to $9,000.

Natural diamond, for the same stone $15,000. up

diamonds, and have the same famous Mohs hardness of 10.

Nobody can tell apart form a La Diamond from Natural Diamond

only a experienced Jeweler.

can set in 14kt gold or sterling silver

Lab diamonds have a beautiful sparkle better than a natural stone!
