Since the lab grown diamonds go through the same conditions like the mined diamonds, they are totally comparable to earth mined diamonds. Lab grown diamonds display exactly the same Physical, Chemical & Optical characteristics like Earth Mined Diamonds. The only difference is that the Lab grown diamonds are engineered in a laboratory above the earth.

With evolving improvements to the techniques and machinery involved in creating a lab diamond, the price of lab grown diamonds is less than natural diamonds by 60% to 85%, and has even dropped in recent years. Lab made diamonds are cheaper than mined diamonds for two main reasons.
Yes, lab grown diamonds are an assured way of making sure your diamond has been ethically produced and sourced – so in short, lab grown diamonds are more ethical than mined diamonds. Ethical diamonds are in greater demand than ever, as consumers, NGOs and bodies such as the UN call for an end to the trade of conflict diamonds.
Compared to the land used for mining efforts, lab grown diamonds are a less disruptive, more sustainable option than mined diamonds. Having said this, artificial diamonds take a great amount of power to enable their growth – typically between 250 kWh and 750 kWh. This is a figure likely to fall with improved technologies, and already some producers claim their lab diamonds take as little as 20 kWh to grow. More and more lab diamond producers are creating diamonds with solar energy, including some of our trusted suppliers, that produce solar energy to offset the energy used during diamond creation.
