Lab created diamonds, also known as engineered or cultured diamonds, are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust.
All lab grown diamonds are certified by independent diamond grading laboratories such as International Gemological Institution (IGI) & Gem Certification and Assurance Lab (GCAL). The certificates issued are identical to mined diamond certificates with grading of the 4C’s- Cut, Color, Clarity & Carat.
Man-made diamonds are driving positive change by making a difference. Our diamonds have no carbon emission, and cause no damage to the surface of the Earth. Scientists and innovators have spent millions of dollars to invent advanced technologies that create real diamonds in specialized greenhouses. Even though grown diamonds require almost equivalent amount of resources, money, time and energy, they are more economical. An increased number of the new generation is embracing this ethical choice as they are bigger, better and value for money.
Mined Diamonds are essentially composed of pure carbon. But many diamonds contain traces of impurities such as nitrogen or boron, acquired during the course of formation. Those diamonds that contain little or no impurities are Type IIa diamonds. Less than 2% of mined diamonds are Type IIa and hence are the purest & rarest form of diamonds. Some of the famous, large Type IIa diamonds are Krupp Diamond, Cullinan, Koh-i-noor and Lesedi La Rona.
