When were man made diamonds first made and how are they produced in the laboratory?

 The first proven man-made diamonds were made by GE in 1954, under a project codenamed "Project Superpressure."  Later as the industry flourished and new technologies developed, diamonds started being produced in a laboratory. These days CVD technology is used. CVD lab-grown diamonds are produced within a growth chamber. It uses a diamond seed placed inside a sealed chamber heated to over 1,400 Fahrenheit and filled with carbon-rich gases like methane and hydrogen.  These gases are then ionized into plasma. The idea is basically to break down the molecular bond of the gas.  Once the molecular bond is broken down, pure carbon begins to stick to the seed, and a new diamond form.

How to Read a Clarity Grade in Diamond Grading Report?

Lab grown diamond undergoes a grading process, and GIA and other organization have been grading lab-grown diamonds. It gives the certification report, which includes a clarity grade scale.   This clarity grade scale is divided into 6 categories and 11 grades when seen under 10x magnification. The categories and grades are   Slightly Included (SI) – diamonds have noticeable inclusions. It is divided into 2 grades: SI and SI2 .   Flawless (FL) – diamonds have no inclusion   Internally Flawless (IF) – diamonds have no inclusion and minor blemishes on the diamond surface.   Very, Very Slightly Included (VVS) – diamonds have minute inclusion. It is divided into 2 grades: VVS1 and VVS2   Very Slightly Included (VS) – diamonds have minor inclusions. It is divided into 2 grades: VS1 and VS2 .   Included – diamonds have apparent   inclusion. It is divided into 3 grades I1 , I2 , and I3

What is There in Diamond Certification Report?

  Lab-grown diamond undergoes a grading process, and GIA and other organization have been grading lab-grown diamonds. In GIA gives a certification report which includes the following terms to identify Color Clarity Type of process used CVD HPHT AT GIA, Lab-growndiamonds undergo the same grading process as natural diamonds. When GIA receives a stone for grading, it undergoes various analysis methods such as observing inclusions, fluorescence, and phosphorescence.

What are synthetic diamonds?

  Lab grown diamonds are as real as diamonds mined from the earth. Laboratory made diamonds are identical to earth mined diamonds in every way, except that they are grown in a lab. They have the same chemical, physical, and optical properties as mined diamonds and exhibit the same fire, scintillation, and sparkle
