How are lab-grown diamonds created?

These synthetic diamonds are produced by two main processes: Chemical Vapor Deposition (CVD) or High-Pressure and High-Temperature (HPHT). These processes mimic the natural diamond formation by subjecting the carbon atoms to great heat and pressure, making gemstones whose chemical, physical, and even optical properties are the same as what is mined.

Are lab-grown diamonds real diamonds?

Completely. Lab diamonds are exactly the same as mined diamonds—chemically, physically, and even optically. They have the same carbon crystal configuration, thus their clarity, hardness, and sparkle are virtually identical. institutes like IGI and GIA certify them as original diamonds, but instead mark a difference between the two on the basis of their origin.

What makes lab-grown diamonds more sustainable?

"Cultivated diamonds in the laboratory virtually erase any environmental impact, unlike mined diamonds. They decrease the consumption of water, carbon emissions, and avoid disturbing an ecosystem or its habitats. For every 0.028 metric tons of carbon dioxide emitted by one carat of laboratory-created diamonds, mined diamonds produce about 1.5 metric tons.

How do lab-grown diamonds compare in price?

Basically, lab-grown diamonds are majorly sold between a price range of 30% to 50% lower when compared to the natural mined diamonds of an equivalent standard. These differences, however, are because of the better production processes, shorter supply chains, and lower extraction costs.
