Lab-grown 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.

Zenith - The Celebration of Human Spirit and Innovation

Smiling Rocks wants to celebrate the new Era of technological advancement with all of you. Its remarkable to be a part of the new change in our industry. We believe Zenith is the first ever lab-grown diamond painting commissioned to Reena Alhuwalia by Smiling Rocks.

Certified Quality & Laser-Inscribed Diamonds

Our lab-grown diamonds are graded using the standard 4Cs method of assessing diamond quality. We provide International Gemological Institute (IGI) certification for larger 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.
