They are Diamonds for the future: affordable, sustainable and a brilliant achievement of human technology and intelligence.
What is the difference between a laboratory grown and an earth mined diamond? The answer is almost nothing in terms of physical properties. A lab-grown diamond is a diamond, with the same physical, chemical, and optical properties as a mined diamond. The only difference is their point of origin – in the ground for a mined diamond, above the ground for a lab-grown diamond – and the different impact each has on the environment and on the people working to produce them.
Even the most experienced gemmologists can have trouble telling the difference between modern lab-grown diamonds and earth-mined diamonds. Lab diamonds have the same crystal structure, chemical composition, optical properties, and physical properties as a mined diamond: both are composed of carbon atoms arranged in a cubic crystal structure.
Rather than forming in the depths of the Earth’s mantle, a lab-grown diamond is created in the controlled environment of a laboratory. The first attempts to grow a diamond go back to the 1950s, but it’s only in recent years that scientists have succeeded in creating diamonds of sufficient quality to be mounted in jewellery.
