Smiling Rocks Diamonds
About Our Diamonds
Lab-grown diamonds made with a smile.
Diamond in every way
Lab-grown diamonds are diamonds with the same 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.
Certified Quality
Our diamonds are graded using the standard 4Cs method of assessing diamond quality. For larger diamonds, we provide certification by International Gemological Institute (IGI) certification.
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.
