Lab-grown diamonds are not imitations or simulants. They have the same physical, chemical, and optical properties as mined diamonds - the only difference being their origin. The journey of these diamonds begins in a lab using methods such as High-Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD), which recreate the conditions under which diamonds naturally form deep within the Earth's mantle.
At Carat Spark we only sell hand selected CVD Lab Grown Diamonds which offer less yellow tint within the diamonds.
In 1954, General Electric, the company known for making your kitchen fridge, achieved a significant milestone by successfully creating the first-ever man-made diamond. However, these diamonds were not intended for their aesthetic beauty; they were primarily produced for industrial purposes. Industrial diamonds found extensive application in lasers and abrasives. It wasn't until the 1970s that General Electric introduced the world to the first gem-quality HPHT diamond.
While it does cost money to grow a lab grown diamond, it is less than what it takes to mine a natural stone. As such, those savings are passed along to you, the consumer. Typically, a lab grown diamond with the same specs (4C's) as a natural will cost about 1/3 to 1/4 of the price.
