Lab diamonds (also known as man-made or synthetic diamonds) and natural diamonds have the same physical, chemical, and optical properties. They are both considered real diamonds. This is because they are both made of carbon and are arranged in the same crystal structure. Here are the differences between the two.

Origin:

• • Lab Diamond: Created in a controlled laboratory environment using advanced technological processes like High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).
  • Natural Diamond: Formed deep within the Earth’s mantle over billions of years under high pressure and temperature.

Production Process:

• • Lab Diamond: Can be produced in a matter of weeks or months using either HPHT or CVD methods.
  • Natural Diamond: Requires volcanic eruptions to bring them closer to the Earth’s surface, from where they are mined.

Price:

• • Lab Diamond: Typically less expensive than natural diamonds of similar quality because of lower production costs and no mining expenses.
  • Natural Diamond: Usually priced higher due to mining costs, long supply chains, and perceived value associated with rarity.

Inclusions and Imperfections:

• • Lab Diamond: Inclusions in lab diamonds might be different from those found in natural diamonds. Some lab diamonds may have inclusions unique to their production process.
  • Natural Diamond: Contains inclusions or imperfections (like feathers, pinpoints, clouds) that have occurred naturally over time.

Identification:

• • Both types can be differentiated using specialized equipment. For the naked eye or even under a jeweler’s loupe, it is often very difficult to tell them apart due to their identical properties.
