What are Lab Grown Diamonds? 

Many people may misunderstand the name to mean that lab created diamonds are fakes. On the contrary, these diamonds have the exact properties of natural diamonds. Just like a clone of a living thing would have the same DNA as the original, LGD- as they are also known, are the result of putting fragments of diamonds through the same process that natural diamonds undergo. Natural diamonds are exposed to heat and pressure over hundreds of years. Those in the lab however have this process accelerated and controlled so that they can be formed much faster.

LGD therefore, look just like the natural diamonds but save the manufacturer and the buyer the guilt of knowing that the precious stone they possess may have been mined at the cost of local’s blood, the environment and may have burned a big hole in their pocket.

The past five years have seen a substantial increase in the number of lab grown diamond manufacturers. Naturally, this means that the market share of these gemstones made in a lab is also steadily increasing. By 2019, China claimed the record for the largest producer of lab created diamonds.
