Do lab grown diamond look different?
To the naked eye, lab diamonds look exactly the same as the mined ones to even the most trained and experienced jewelers and gemologists. Because synthetic diamonds have the same physical and chemical properties as natural diamonds that cannot be discerned by the naked eye alone. And lab created diamonds cut and polish specifications, like natural diamonds, are also divided according to the 4Cs. Therefore, to distinguish, experts need to use specialized equipment to decipher the physical and spectral differences with natural diamonds.
What is high pressure and high temperature?
HPHT, the full name is High Pressure High Temperature, that is, high temperature and high pressure. To be clear, the term HPHT has two concepts in diamonds: HPHT lab-grown diamond and HPHT treated processed. For example, brown diamonds can be turned into yellow or colorless through HPHT treatment.
Man made diamond by high temperature and high pressure method refers to simulating the growth environment of natural diamond, using graphite, diamond powder or graphite-diamond powder as the carbon source, forming an equiaxed crystal in the growth environment of high temperature and high pressure, metal catalyst, etc., referred to as HPHT synthetic diamonds, or HPHT cultivated diamonds.

Are lab created diamond Real?
Sure. There is no obvious difference between the Lab Grown Rough Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
Carat 1
The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality, a single two carat diamond will be more expensive than two one-carat diamonds of the same quality.
Color H
A diamond’s color is an important element of its quality. In a white diamond, the less body color present, the greater the value of the diamond. The GIA grades diamonds on a scale of D (colorless) to Z (noticeable color).
The predominant color you see in a diamond is yellow, which is caused by the trace element nitrogen.
Clarity SI1
Clarity refers to the presence of imperfections, flaws and blemishes inside or on the surface of a diamond.
The GIA grades diamond clarity under 10X magnification on a scale that ranges from Flawless (FL) to I2-3 (Included). Diamonds with the least amount of flaws having the highest clarity grading.
A diamond’s clarity has a significant impact on its value.
Cut Very Good
The cut of a diamond influences how effectively it reflects light. Well-cut diamonds appear fiery and brilliant and allow light to enter the stone and be reflected around the facets before exiting the stone through the top. Poorly-cut diamonds can appear lifeless and dark, despite their clarity or color grade.
Not only do well-cut diamonds appear more brilliant, they also tend to appear larger than other diamonds of the same carat weight.
