Each C-® Diamond possesses properties indistinguishable from mined diamonds, with one crucial distinction: our gems are cultivated in carbon vapor deposition (CVD) reactors powered exclusively by renewable energy. This innovative process marries the timeless allure of diamonds with cutting-edge, sustainable technology.

We exclusively promote the Production and Sale of Carbon Negative Diamonds. All of our partners are required to verify that the energy used in the production of C-® Diamonds is sourced from non-carbon-emitting renewable energy.

Every C-® Diamond has the same chemical, physical and optical properties as mined diamonds.
