Lab grown diamonds are often confused with simulants and lab created diamonds. But there is a striking difference between the three. Lab created is a broad term used for diamonds which have not originated from the Earth’s core.

Lab grown diamonds are physically, optically and chemically same as earth mined diamonds, except that they are grown in a controlled environment inside a lab, replicating the same process that occurs inside the Earth’s crust. Lab grown diamonds are grown over thin layers of natural diamond and layers of carbon are deposited through Chemical Vapor Deposition (CVD) technologies. They are so identical to earth mined diamonds that it’s impossible for naked eyes to tell the difference. Only labs with the most sophisticated technologies like IGI and GIA can tell the difference.

On the other hand, simulants are diamond look-alikes and are made from Cubic Zirconia, also known as CZ. Moissanite is another simulant made of crystal carbide and has more fire than Cubic Zirconia. Both the simulants replicate the crystalline structure of diamonds but are chemically very different from pure diamonds. Though lab created, these simulants change their properties over time and may change color as well. Lab grown diamonds are pure carbon diamonds and they last as long as earth mined diamonds.

CVD is the acronym for chemical vapor deposition. This means that a material is deposited from a gas onto a substrate and that chemical reactions are involved. Diamonds prepared by CVD techniques are CVD Diamonds.

HPHT is the acronym for High Pressure High temperature. HPHT diamonds are subjected to extremely high temperature and pressure inside special machines in a lab. The exorbitant cost of the energy and machinery required to perform such a task results in a very desirable product—a colorless lab grown diamond.

GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.

They are absolutely real. Grown in a lab under perfect conditions, they have the perfect cut, color, and clarity—the standards by which mined diamonds are graded. They feel and wear same as mined diamonds. Moreover, they are an eco-friendly and ethical alternative to purchase.

Lab grown diamonds are indistinguishable from flawless, colorless mined diamonds. Only Labs like IGI, GCAL and GIA with the most sophisticated instruments can tell the difference.

Yes, lab grown diamonds can be graded according to the 4c’s. In fact, they are totally identical to mined diamonds in all the four parameters.

This is a term used for diamonds mined in war zone. These are diamonds used by rebel groups to finance civil wars. However, besides civil wars, diamond mining today is plagued by a range of shocking ethical abuses. These include violence by governments, child labor, extreme poverty, and environmental devastation. These diamonds are sometimes referred to as "blood diamonds."
