Rough Lab Grown Diamonds Description
Many people refer to Lab Grown Diamonds as 'fake' diamonds, but
this is not accurate. The carbon based chemistry of Rough Lab Grown
Diamonds means that they are actually "real" diamonds - unlike
cubic zirconia or moissanite.
These diamond simulators are also made in the laboratory, but they
are not made of carbon atoms, so they are not real diamonds.
Simulates are not as shiny and shiny as real diamonds. There are
also differences in hardness. Diamond scores 10 on the Mohs
hardness scale, while moissanite scores 9-9.5 and cubic zirconia
scores 8.
What is a lab-grown diamond?
Lab diamonds are real diamonds. Lab-grown diamonds after polishing
and cutting are no different from natural diamonds.Carbon is the
main element of natural and laboratory-grown diamonds.
The HPHT synthesis method is a more traditional diamond cultivation
method that uses molten metal alloys such as iron (Fe), nickel (Ni)
or cobalt (Co) to form diamonds.
The CVD synthesis method is a relatively new method of cultivating
diamonds. The vacuum chamber is filled with carbon-containing gas.
A carbon plasma is formed at the bottom of the vacuum chamber. The
plasma is continuously deposited on the carbon bottom layer at the
bottom of the pressure chamber. For several weeks, the resulting
flake crystals usually have black rough edges, and the crystals
often appear brown, but they can be removed by heat treatment.
Since 2014, the production of laboratory-grown diamonds has
progressed rapidly. Today, the cost of cultivating diamonds in the
laboratory is significantly lower than that of natural diamonds.
And synthetic diamonds of all sizes can be cultivated in the
laboratory, from extremely small diamonds (round diamonds with a
diameter of 0.5 mm) to more than 10 carats, it is not difficult to
reach. In particular, small diamonds (melee diamonds) have been
mass-produced and used in jewelry setting.

Rough Lab Grown Diamonds Introduction
Rough Lab Grown Diamond is a polycrystalline diamond made of
diamond crystals with a diameter of 10 to 30 nanometers. In the
early stage, man-made diamonds showed a light color of sugar due to
the nitrogen atoms in the air entering into the diamond crystal.
Through the improved production method of scientists, there is no
difference between man-made diamonds and natural diamonds in
appearance now.
