What is a Lab Grown Diamond? 

Lab-grown diamonds are physically and chemically identical to natural diamonds, but they have been created using tiny “diamond seeds” and carbon. The results are indistinguishable from natural diamonds, even to the most experienced jeweller! Not only do lab-grown diamonds allow us to literally grow perfect glistening jewels to use in the most beautiful engagement rings, necklaces, earrings and other jewellery pieces, but they negate the need for often controversial mining practices. The lab-grown diamonds for sale at CJL Diamond Brokers are stunning, truly high-quality gems that we are proud to showcase in a wide variety of jewellery. Browse our collection of bangles, hoops, solitaire rings, bracelets and pendants to see with your own eyes the quality and clarity of these precious jewels.  

How Are Diamonds Grown in a Lab? 

There are two methods currently used to produce lab fabricated diamonds: HPHT and CVD. In fact, it was the high pressure high temperature (HPHT) process that was used by General Electric to produce the first synthetic diamond in 1954.  

HPHT works just as you’d probably expect, by adding extreme heat and pressure to a tiny diamond fragment (diamond seed) and carbon. These conditions cause the carbon to break up and crystallize onto the existing diamond, growing in a matter of weeks what the Earth produces in no less than 1 billion years.  

Chemical vapour deposition (CVD) may also use a diamond seed, though it can be done with a solid carbon seed as well. These seeds are surrounded by carbon gas and superheated until the carbon precipitates onto the seed. It takes about 2 weeks to create a diamond from the CVD process, though another heat treatment is needed to change these from yellow to white diamonds. 


Why Choose a Lab-Grown Diamond? 

The traditional method of land survey, mining and diamond acquisition is expensive and not particularly environmentally friendly. Lab cultured diamonds, on the other hand, are relatively inexpensive and totally clear of industrial mining and any economical or social issues that often plague the gemstone extraction industry. At CJL Diamond Brokers, we’re pleased to offer these ethical and affordable diamonds to you, our customers!

Lab-grown Diamonds Vs. Real Diamonds  

Lab-engineered diamonds are real diamonds in every sense of the term, and undistinguishable from natural diamonds mined from the ground.
