A Diamond in Every Way

Lab grown diamonds offer exceptional brilliance and value and are a responsible choice because no mining is required.

Lab grown diamonds offer excellent value and are slightly more affordable than natural diamonds of comparable size and quality.

Lab-grown diamonds are diamonds with the crystal structure, chemical composition, and physical properties as the mined rocks: carbon atoms arranged in a cubic crystal structure. They are grown in labs, with advanced technological processes that stimulate the same conditions under which mined diamonds develop when they form in the mantle, beneath the Earth’s crust.

Lab-grown 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. These man-made diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties. 


Certified Quality

Lab-grown diamonds are graded using the standard 4Cs method of assessing diamond quality.  For larger diamonds, certification by International Gemological Institute (IGI) certification is provided.


Laser-Inscribed Diamonds

Identification is important to us and is a representation of our quality mark. We have laser-inscribed Smiling Rocks logo and is only visible under a microscope. Smiling Rocks logo is inscribed on the surface on each diamond as our assurance on excellent quality.
