TECHNOLOGY: THE SCIENCE BEHIND PERFECT REPLICATION OF MINED DIAMONDS
- HPHT or CVD: With the help of HPHT or CVD process, the diamond growing conditions can be replicated.
- DIAMOND SEED: In the CVD process, carbon crystallization over a diamond seeds can be replicated in a vacuum chamber. Methane (CH4) and Hydrogen (H2) gases are used in this process and both the gases have a significant impact in the process. Methane is a source of carbon inside the vacuum chamber, while Hydrogen assists in creating extreme high temperature environment inside, needed for the growth.
- CRYSTALLIZATION: Mimicking the natural process, carbon crystallizes on the diamond seed and forms a tetrahedral structure similar to the structure formed below the earth's surface. The carbon atoms of gaseous state transforms into a solid state as a single crystal, forming a diamond.
Similarity Between Diamond Grown By CVD or HPHT Process & Plants Grown In Greenhouse?
The plants grown inside and outside the greenhouse have fruits and flowers, with exact sweetness and prettiness. Similarly, KBK grown and polished synthetic diamonds are “greenhouse diamonds”, as real and as pretty as mined diamonds. The only difference between mined and KBK grown and polished diamonds, is the point of origin.
Synthetic Polished Diamonds vs Natural Diamonds
you happen to be among people who confuse synthetic diamonds, then its
time to clear the misconception first, as synthetic or laboratory grown
diamonds are in no way different than their naturally mined counterparts
in terms of their chemistry, molecular structure, and to an extent,
their physical properties. The only difference between the two is that
natural diamonds are produced over millions of years by slow carbon
transformation under tremendous heat and pressure, while synthetic
diamonds are created in laboratory by using carbon sources like methane
and creating the same conditions, albeit to a higher magnitude, to
hasten the process of pure carbon formation and its eventual conversion.
Moreover, in terms of aesthetic and superficial attributes, they
exhibit nearly the same levels of brilliance, luster and crystal
clarity, all that in a form that can also be customized and cut as per
your specification, which is something that real diamonds can not
provide, that too, at prices that are mere fractions of the hefty
premium that real diamonds command.The synthetic diamonds have similar properties as of mined diamonds, like:
- C Chemical Composition
- 10 Hardness
- 3.52 Gravity
- 2.54 Refractive Index
- 0.044 Dispersion
can not find the difference between the two with the use of a loupe,
gem microscope, thermal diamond tester, refractometer, or polariscope.
mined and lab grown & polished diamonds are certified based on 4C's and
We are mainly export to USA.
