Lab-Grown Diamonds.


Lab-grown diamonds are real diamonds that are created in a laboratory, using one of two methods:
High-Pressure High Temperature (HPHT)
This method mimics the natural process of diamond formation deep within the Earth. A capsule containing a carbon source and metals is heated to temperatures of 2400–2900° F under pressures of 5–6 GPa.
Chemical Vapor Deposition (CVD)
This method uses a near-vacuum pressure to heat hydrocarbon gas into plasma, which separates the carbon atoms to create a diamond crystal.

Lab-grown diamonds are identical to natural diamonds in terms of their chemical and physical properties and can receive the same certification from the Gemological Institute of America (GIA). They are available in a range of colors, including colorless and rare fancy colors.

To prevent confusion, the FTC requires that all lab-grown diamonds be engraved with the letters "LG" for lab-grown. You can also check for a laser inscription or lab report number on the girdle of the diamond. If there's nothing on the girdle, only a gemological laboratory can tell you if the diamond is lab-grown.

Some potential drawbacks to lab-grown diamonds include: 
  • They may not retain their value in the future.
  • They require a lot of energy to creat.
  • Some people prefer natural diamonds.
