Lab grown diamonds or lab created diamonds are developed in a lab using cutting-edge technology under controlled conditions and grown within sophisticated laboratories with controlled environmental parameters that replicate the growth process of a natural diamond inside the earth’s crust. Lab Grown Diamonds are Eco-Friendly to the planet, Conflict-Free, and Sustainable These aesthetically appealing diamonds are optically identical with natural diamonds, but are way less expensive than the natural ones. Lab grown diamonds are also known as engineered diamonds, cultured diamonds and at times also referred to as lab created diamonds. Lab Grown Diamonds uses chemical vapor deposition (CVD) to grow diamonds.
